Solstice

If you find yourself adventuring alone in the high snow-capped mountains that this dragon calls home, you had better pay close attention to your coin purse. Quick as the wind and nimble as a fox, the only way you'll catch a glimpse of this dragon is by the flash of red that streaks by in a cold gust of wind before your wallet becomes unnaturally lighter.
Mysterious in his ways, the air around this dragon always seems to be a bit cooler than anywhere else. His breath is always visible as it swirls around him in thick white curls. Some say his eyes are as white as snow, glittering madly as it does just before snow-blindness strikes. Others say they are the same shade of grey as the storm clouds that blot out the sky in a gale of wind, dark and unforgiving. Whichever it is, they are captivating, enough to stun any dragon to silence if they meet his gaze.
With the help of his sticky fingers, this solitary male has amassed quite a collection of gold coins that he hoards in small stashes high in snow-covered trees. Not much of a fighter, he instead relies on his speed to get him out of tricky situations. Luckily for any travelers to come across his path, the only thing in real danger of this dragon is your coin purse.
