“Smaug lay, with wings folded like an immeasurable bat, turned partly on one side, so that the hobbit could see his underparts and his long pale belly crusted with gems and fragments of gold from his long lying on his costly bed.”
And later:” He noticed that there was a large bare patch in the hollow of his left breast the size of a robin's egg not covered by his breastplate of gems.”
The Hobbit; J. R. R. Tolkien
So that is Mythic Games’ Legendary Dragon for Time of Legends, Joan of Arc done and dusted.
In the game, the Dragon is meant to be a medieval manifestation of Satan himself.
Now Satan is nothing if not vain. Why not manifest with a coat of gold and diamonds, and why not leave a bare spot on his most vulnerable part in order to taunt those pesky humans?
In any event it works for me as a multi-purpose dragon.
Hope you like it!
