Its a long forgotten race called the Fenice.
Fenician people are a race of humans, gifted with the power of the Phoenix.
At first glance, they looked like a normal human, but their bright red hair is what makes them noticeable.
Every Fenician has a red hair, and has the power to grow red wings on their back, those wings are able to take them to the sky, that's why most of the Fenician wear clothes that has open back.
They live deep inside the south jungle, making almost no contact with the others.
Other than flying, Fenician is invulnerable to fire, but is extremely weak against waters.
The Fenice learned early on that the fastest way to develop and profit is for their people to be happy. A happy person is a productive person. This is why they have freedom of expression and individualism (as long as you are a Fenician).
However, most, if not all of the dominant Fenician are members of Houses. Houses are congregations of individuals who share the same blood (family ties being taken very seriously by Fenician) and/or interests (wealth and power being taken much more seriously by Fenician).
Success breeds success, and while Fenicians promote individual achievement, over the years, the same families harvest most of the wealth and power. Influential Fenicians then lend money, offer services or help to lesser ones, for the conduct of their business or other matters, and strong ties develop between all sides. Soon enough, it is a vast network of interests that emerges. A House. Several networks can intertwine, of course, but the core of every one of them is a powerful and identifiable family that will do its best to keep the relatives, allies, and clients in line with the Houses interests.
