Far off of the coasts of the mainland Fizzy Bubble zones, remote in the Silver Ocean, an island chain sits in basically, the middle of nowhere. These islands contain the some of the most diverse typing of Pokemon in the entirety of Fizzy Bubbles. All of these islands are actually volcanoes, but the majority of them have gone dormant. As many Pokemon spend all their lives here, many fossils of Pokemon and plants are buried in the depths of the volcanic ground, maybe some of these may be worth a look? You start out on the island that you first choose, via a ferry. In order to change areas afterward, Surf or Fly is a necessity.
An active volcano, this is the largest of all of the islands of Cascadia. Continually pumping lava out of human-built channels into the sea, the volcano causes the island to continually become larger and larger. Fire, Ground, and Rock types are common in these areas, and there are a few volcanic caverns leading into the volcano which are of interest to many people, and are said to house rare and powerful Pokemo. There is also a small village on the opposite end of the island, and the natives appear to be friendly, as long as they aren't disturbed too much. Vegetation on this island is sparse, and only the hardy plants can survive the heat of the volcano. The sand along the beaches is pitch black, and isn't exactly the softest thing to walk barefoot on. Hot springs and geysers are common in this area, dotting the landscape of the giant smoking mountain.
Ebony Beach - Surrounding the island, black volcanic beaches stretch along the shoreline. Actually volcanic ash, this is rather hard on the feet for those who choose to go barefoot. Chances are you won't find much in the water, with the volcanic rocks releasing chemicals into the water that leave living conditions less than favorable for most Pokemon, though some embrace the conditions.
The Lithogic River - The 'river of fire' in native settler terms, the Lithogic River is a large channel of lava being carried from the rim of Mount Aduro down to the sea. A few fire types hang around this area, and it's been said that the lava has cooled into rare gems in some parts.
Aduron Chasm - Atop Mount Aduro, the Aduron Chasm is the rim of the volcano which overlooks the boiling bowl of magma underneath. Fire types of all kinds thrive in the immense heat.
Geyser Park - A particularly interesting region, a part of the island has been converted into a park in which a dozen or so large geysers spew boiling water from the ground almost simultaneously, providing a breathtaking sight. This is pretty much the central hub of the island.
With a totally different landscape from the first, Lily Island is the second largest of the archipelago. Completely covered with vegetation, this island was also formed by a volcano. However, erosion has taken this island down to almost flat, and giving many homes to all types of grass and bug Pokemon among others. Inside the dense jungle, which takes up about a half of the island, there is a very small lake. There are two different forests on the island, and you can tell when you've gone from one forest to another. Besides being divided by the Diamond River, some strange force causes them to have completely different climates as well...
The Silver Forest - The forest which takes up a bit more than half of the island, Silver Island is named for the silver veins the leaves are adorned with. A deciduous forest, you'll mainly see flying and bug types here, due to the lack of ground vegetation. There is a rest stop somewhere in the forest, helping trainers on their way.
The Diamond River - A fast flowing river that cuts through the two forests, the Diamond River is named so because of the crystals in the lake bed, which cause the water to seem to sparkle. These crystals look very valuable, though the fast running currents many make them hard to reach. The river is about 8 feet deep, and 10 feet wide. Its source is the mysterious lake in the Red Forest, while it empties into the Silver Ocean.
The Red Forest - Quite possibly the most dangerous of all of the areas in Cascadia, the Red Forest was named after the savage conditions it provides. Many ruthless and savage Pokemon live in this dense rainforest, of which many attack without warning. There's no telling what types of Pokemon you may find here. It is said that a small freshwater lake is somewhere in this forest as well.
Named by the first of the explorers to the island chain, Glacier Island isn't even an island. It is basically a large iceberg sitting in the middle of the sea, which has provided a home to many ice types. Many have attempted to find out why the ice doesn't melt, but each of them has failed in turn. This is just one of the mysteries of this island that go unsolved. Possibly some clues lie in the depths of the iceberg?
Boreal Wastelands - Covering the top of the iceberg, this area is basically a barren wasteland, devoid of life. There is a research base somewhere on the iceberg, but if you are unfortunate enough to get stuck in the middle of a blizzard, you may have to rely on your own abilities to be able to survive it. Ice Pokemon thrive in the conditions.
Icicle Caverns - Dug by scientists and explorers, a large cavern dips deep into the ice chunk branches off into two a bit in. The temperature in here is much colder than the outside, reaching -50 degrees (F). This alone makes it hard for most Pokemon to endure, but the lack of light also makes this a very difficult area to explore, but the benefits are said to be worth it, as adventurers have returned bearing treasures.
Hiel Research Base - As the only permanent settlement on Glacier Island, Hiel Research Base provides a place to resupply for all, if you're fortunate enough to locate it.
Like the other islands of the archipelago, Crater Island is an inactive volcano. After what seems to be an excessively violent eruption, the empty crater filled with water, forming a lake. Many water types of many types live in the fresh water lake, and there are legends that some things lie in the depths of the lake...Possibly underwater caverns?
Iridi Beach - Formed by some strange mineral, Iridi Beach's sand is a very bright, sparkly white. Rather than black, like most volcanic sand, this is more of the sand you might find at a normal beach. A few sunbathing Pokemon who venture from the water may be found here, but mostly, this is just a tourist attraction.
Pearl Lake - Extremely, extremely deep, this freshwater lake holds all kinds of water Pokemon. There's absolutely no telling what you'll find under the calm surface of the water. Legends of deep sea treasure exist, could they be true? One thing is for sure, large colonies of Clamperl make this their home, providing the number one source of pearls in the world.
One of the more interesting areas of the archipelago, Ruin Island is also the most mysterious. Giant stone statues and buildings, eroded by time, stand in the overgrowing vegetation of the area, providing a home to many Pokemon, especially those who prefer dark, enclosed spaces. Studies done by researches show that this island was once under water, or flooded, or something. At the very least, they have established that it is the oldest of the areas. An eerie feel of foreboding rushes over one the second they set forth on the land, provoking myths and legends...
Elegy Fields - At some point it appears as though humans lived on this island. Here is where they apparently buried their dead - eroded away tombstones are plentiful here. Travelers have sworn to have seen ghosts of the deads' restless spirits haunting the land.
Amor Temple - An abandoned temple near the center of the island, plants have overgrown it and many dark and psychic Pokemon have taken the temple to be their home. Many tricks and turns lie around each corner and stairway, and one mistake could be your last...
Ordial Shrine - Dubbed as so by explorers, the Ordial Shrine is, or was, at least, a stone shrine used by the ancient peoples to honor their gods. The rock is stained red with the blood of those sacrificed for the ancients' rituals.
Oniero Ruins - Another of the strange ruins of the island, the Oniero Ruins are a series of large, white rocks placed in a circle around a black rock in the middle, which is said to have powerful properties if touched. However, as one enters the ring, they find themselves in a dreamlike state, making this a rather interesting part of the island.
Ion Island is made of almost entirely iron ore and magnetic substances that conduct electricity easily. It is said that long ago, a huge battle which pitted two powerful electric Pokemon electrically charged the island, causing most Pokemon that lived here to die. However, electric types thrive here, and recently people have learned how to use the electricity to their own use.
Eletron Plant - A large power plant at the center of the island, large metal rods are drilled into the ground, causing the electricity to flow up into and through large thick wires that go along the bottom of the sea the entire way to Brine Island, and power Salin City. Electric Pokemon hang around here, as well as scientists who will often ask for help in finding something.
Storm Lake - A crescent moon shaped lake that surrounds the north and east sides of the Power Plant, Storm Lake is an electrically charged freshwater lake. Only a few Pokemon live inside the lake, but many electric types come to cool off.
Thunder Fields - Across the south section of the island, large fields are constantly rained down upon by large thunderstorms. The majority of the Pokemon in this island hang around here, but take caution if you decide to journey here.
Quite possibly the least attractive area of the entire island chain if you don't have a specific purpose, Venom Island is the epitome of all things putrid. The ground itself is saturated with poisonous substances. Also, all of the garbage from Salin City is transported here, but it is hardly noticed, as the acidic ground eats away at anything at a very quick pace. However, that means that not many things can live in this desolate area, with only a dead tree forest, a poisonous swamp, and a large skull tunnel interupting the landscape. The rest of the island is just plain dirt, but a good amount of poison types inhabit the area. The water surrounding the island is so poisonous that Pokemon cannot swim in it-therefore, unless it is a poison type, it cannot Surf to this area.
Skull Tunnel - Taking up small amount of the island, the top of Skull Tunnel is a giant white rock formation, shaped like a skull. However, Pokemon have dug tunnels far underground from the Skull. Poison and ghost Pokemon call this area home, and the tunnels are pitch black, so unless you'd like to wander around aimlessly, bring something with Flash.
Plague Swamp - Taking up a good amount of the island, the Plague Swamp is...a swamp. However, the water is extremely poisonous, making only some Pokemon even able to live here. However, not many even choose to that can, because the entire thing is covered in a thick fog, and most people that venture in don't ever come back out. Pokemon are said to lure travelers into deep areas of the swamp, and they get stuck, before drowning.
Bane Forest - Bane Forest, apparently, used to be a prosperous forest, much like Lily Island's Silver Forest. However, as the poisonous ground was formed, the forest died from the inside out, the trees becoming poisoned, and dying. Some toxins in the poison stopped the trees from decaying, leaving them gray and hard as rock. A few rare Pokemon live in the area, but there is also legend that something valuable is hidden inside one of the trees...
Salin City - The only real city in the entire island chain, Salin City is huge. Taking up the entirety of Brine Island, Salin City has everything-from shopping places, to schools, hospitals, a Pokemon Center, an airport, and a seaport, among other things. There is a small park in the middle, with a fishing pond and a few trees scattered about. Stands line the streets wishing to sell you things, and it'd be pretty hard to not find something to do. But if you would happen to find yourself in such a dilemma, there is a Pokemon Gym in the city which holds eight leaders, one each to symbolize the Cascadian Archipelago. However, only one may be challenged per visit to the gym.
Coral Harbor - Where the city can really attest its roots from, Coral Harbor is a natural formation of coral in a pair of parallel lines perpendicular to the island. These natural boundaries protect the area from most rip currents and the like, allowing for ships to load and unload their goods. Many Pokemon also live along these, creating a popular tourist attraction.
And last, but not least, the Silver Ocean. Completely surrounding the entire chain, the ocean is usually very calm. Named so because it is believed that Lugia rests somewhere in the depths, perhaps you may wish to look around at the areas? A large shipwreck lies just off of Ion Island, and that appears to be the most interesting of the areas. Surf is needed to explore above water, Dive is needed below. While these areas below are the most prominent, you're free to just surf along the surface or fish for Pokemon.
The SS Leviathan Shipwreck - A few hundred yards from Ion Island, the mast of the SS Leviathan jets out of the water, the only visible from the surface testament to the shipwreck that happened abour 50 years ago. There are rumors that treasure had been found, but then lost deep in the ship...Could they be true?
Seaweed Fields - Covering most of the ocean floor, seaweed provides a natural hiding place for all sorts of water types. All sorts of Pokemon live here, so whether you're catching or just training, this is a good place to start.
Deprimo Trench - About a mile away from Ruin Island, a very deep trench lays at the bottom of the ocean. The deepest point in the Silver Ocean, Deprimo Trench holds a few sturdy, but strong, Pokemon able to survive the immense water pressure. It's pitch black down here, though.
Auronos Caverns - Deep below the surface of the Silver Ocean, several caves are scattered along the seafloor, each of them leading into a complex series of undersea caves. It is said that the one who can find their way to the so called "Treasure Chamber" will find prizes beyond their imagination, though one would have to get through the perils the caverns hold first...
Now then, pick an area, and let your adventures begin!
