Children of the Fallen Sun

From the publisher:

The star fell from the heavens, its long red tail ripping the sky like a bloody, dripping wound. All eyes of the tribe—mutant, manimal, and plantient alike—were transfixed by the resulting explosion seen far off in the horizon.
Some proclaim this is the Second Death, foretold within the Ancient Prophecy. But one venerable sentient redwood recognizes it as the Sky Ark of the Ancients, whose mysteries must be explored before they can be exploited by the tribe’s enemies. What perils and mysteries will lay within the Sky Ark? Only the heartiest of your species have a chance of surviving the dangers that accompany the arcane ancient technology developed by the Children of the Fallen Sun.
