This egg is hard to see and cold to touch, as it seems to swallow all light and heat around it.
Elemental crystalwings are strange creatures. Unlike the most well-known (if not most commonly seen) crystalwings that are creatures of earth and air, they display strong affinity for a specific element the moment they hatch, and actively seek out magi with similar affinities to partner with. Sometimes if an elemental crystalwing does not find a suitable magi, it will even seek out a creature with similar powers as a companion instead. This is uncommon, as elemental crystalwings are highly useful magical companions, making spells of their corresponding element far easier to cast in their presence. Magi speculate that elemental crystalwings seek companions so readily because they are rarely seen manipulating their element themselves, seemingly preferring to help exert their will on the world by helping a companion do so instead.
