Gargoyles

The main characters of the series are gargoyles, large winged humanoids (their appearance is vaguely demonic, though saying so is insulting to them) that are extremely (almost literally) nocturnal — they turn to stone, no matter what, when the sun rises. Once, there were many gargoyles, but interactions with humanity have led to their species becoming endangered. The main characters survived a purge in the year 994 thanks to a magical spell that made them permanently statues — at least, unless the castle which they were protecting were to ever "rise above the clouds".
