FIRST OF ALL, THESE ARE TWO DRAGONS, brothers, they're conjoined. Hence the extremely odd anatomy.
Apeirophobia: "Fear of Infinity."
These two dragons were formed in the same egg, the head of the dragon being faster than his sibling spread his wings small wings and filled most of the space, forcing his brother behind him. The brother, wingless but with four legs was formed melded into his brother's back. His body contorted, his head now faces opposite his brother's and out of the back. The brother who's head is shown as they grew found that his body was forcing its way up towards him due to the lack of space. With no where to go his tail was forced into his mouth and cannot be removed, the two brothers share one stomach but it is only the second brother who can feed. The two feed on the unlucky travelers that happen past their cave or who are camped out on their mountain at night. If food is scarce they go to a nearby village to feast on livestock and any villagers foolish enough to be out. Once eaten by the dragons you cannot escape, you enter the void of their body and will never pass on... Or through.
This one is pretty odd, I'm aware... Then again a lot of mythical creatures really don't make much sense. .___.;;;
Custom for ravynarcadiavalos of FA, hope you like it, if you don't like the idea of the extra body below the main one I can get rid of it. Just kind of figured it would be interesting to do conjoined twins.
Once I get the okay on the twins idea I am detailing the body a little more... Didn't want to do all the work and then risk having to get rid of it. xD;;
