Don't go shooting my dragons now. I'm rather fond of them. A dragon and a demon are very different creatures, but some ideologies like to lump them together. Dragons often represent elder wisdom, patience, and strength of both mind and muscle. They usually aren't interested in the affairs of man unless it somehow involves them. If you do happen to catch the attention of a dragon, often the worst you would have to look forward to is playful trickery in hopes you learn a greater lessen. In the myths involving dragons, I'm reminded of the behavior exhibited by the coyote in Native American lore.
Demons on the other hand, I have no use for and am certain are always up to no good. If you see one fire away!!!
Ooops my nerdy side is showing again.
