Raingile

The mountain of a beast shines in the splendor of the sun across the scope of his blue and green scales. Huge green eyes, large as a man, peek out over a long snout, ending in a few white fangs and constant smoke which emits from his nostrils. Floppy red ears contrast the whole of his skin on either side of his face. Long arms and legs end in feet large as a house with claws the size of a tree. His lengthy tail whips round and round, but lacking spikes at the end due to some ancient injury.
This fire-breathing beast lived deep in the depths of mountains for years, being active some just after the world began but then falling into a long hibernation. Only recently has he graced the land once again.
