A bit of mythology:
In the beginning there were two dragons fighting for dominance of the universe: one of light and one of dark. This battle had gone on forever. Both dragons were tired of the battle, and wanted to end their eternal struggle. The Dark Dragon powered up to unleash an attack that would end it once and for all, but in doing so it left itself open to a counterattack. The Light Dragon, seeing the opportunity launched its own attack, defeating the Dark Dragon once and for all. The Dark Dragon's essence would not be denied, however. In attacking , but getting injured... contaminated in the process. The Light Dragon needed to rest, so it curled itself into a ball, creating a type of cocoon for itself. This became the water we see that is most of the planet. Only the dragon's spines are seen..Breathing out it exhaled much of the air from its lungs which surrounded it, thus creating the atmosphere. Creating self-contained floating platforms of vegetation, it filled world with animals, and created the draconic races, to act as its protectors, before going to sleep.
Because these races are actually living on the dragon's life force (and in fact, its body) any attempt to completely heal the dragon would cause an apocalypse that would end the existence of life due to the fact that they were only created for the sole purpose of guarding the dragon while it healed - but the dragon world that made them didn't anticipate things to get so out of hand that there would be any controversy over its reawakening.
There is a faction (religion) of dragons that seek to totally heal the dragon that makes up the planet by eliminating evil and thus bring about a new age of peace and prosperity (kinda a Gaia type of a thing). They feel they're doing the right thing. Good actions, good thoughts, good behaviors help to heal the dragon and hasten its awakening.
There's another faction (religion) of dragons that seeks to cause so much evil and chaos that the dragon will forever be asleep and thus allow life to continue indefinitely. This too would bring about a disaster, as if the evil spreads enough, the dragon would die, also ending the life on the planet because if it dies, so too does all life. War, violence, and every type of evil spreads the corruption, preventing the dragon from healing completely.
There's a third faction (religion) of dragons, which seeks to balance evil and good thus preventing the dragon they're living on from totally healing, but not having it so polluted with corruption it dies.
In this convoluted ideology of good and evil, is it possible to be fair to all sides?
