This cutie is up for adoption! He's a weather pony that specialized in frost and snowflake creation. Luster Dust has a thick coat to endure harsh weather and has done many studies of the many different types of snowy weather Equestria and Beyond experience since each ecosystem is a bit unique. When he flies in sunlight his wings shimmer with unmelted frost that accumulates on the wingtips.
He will be appearing in Baltimare in Sleepy Sketch's story later on as a background pony every so often.
I'd like to get about 15.00 for him but gimme an offer.
