Horizons of Spirit Island

Your island has been your home for more sunrises than the eldest of you can count. As Spirits, you are an essential part of the natural world, but something beyond nature, as well. Native islanders, known as the Dahan, have learned how to co-exist with the Spirits, but with a healthy dose of caution and respect. Your existence has been, for the most part, peaceful.
Now, your island has been "discovered" by invaders from a far-off land. These would-be colonists send their explorers across the island, taking over the land and upsetting the natural balance, destroying the presence of Spirits as they go. Your home is being blighted by their actions!
As Spirits, you must grow in power, draw energy from the natural world, and work together to drive the invaders from your island! Defend your home in Horizons of Spirit Island!
