Comet

About hoard:

He keeps his snowflakes organized in black paged albums so they can be seen clearly on the black surface, and he uses a little bit of his own magic to keep them in perfect condition forever.

About room: 

His room is always a little chilly, he likes it that way, and has a desk where he works on his albums of snowflakes, plus a bunch of somewhat twisted shaped shelves on which he places his albums. His three favorite snowflakes, the biggest, prettiest and best condition he has, are framed on wall over his bed.

About Comet: 

He is quiet and playful in a calm and friendly way. Thoughtful and organized. Rather stay outside gathering snowflakes during winter and estivate during summer.
