Colorful patterns would not develop on an ice world, especially not for hunter species.
Given the examples, I'm highly against making it a colorful hyper-advanced space penguin raptor, in other words, make them come from an actual temperate planet.
I would agree. I kept them on an ice world because Baystation lore, but given their characteristics, it would make a lot more sense to have them be on a temperate, if not tropical world (with snowstorms being replaced with violent rainstorms and thunderstorms, for the biological and technological ramifications of it. Thoughts?)
As a note, in our lore, we have an element not found in other server lores, Teranium, used for high density energy storage, and weapons, and it's presence is known to make extremely violent storms.
Their planet could be mineral rich, especially in Teranium, fueling their technological base, as they wouldn't have the battery issue we currently have in real life; it would also help enhance the tropical storm ideas for why they haven't left their planet.
