If you're curious about the name, it's a nickname I came up with for one of my original characters years ago. Her full name was Zwimrael and she was a cute demon girl. I never really used her much, but the nickname was something I always liked. Also, unlike my old name, it's actually original, as a quick search doesn't find any significant people using the name or fictional characters, etc.
The zergling ain't going anywhere tho!
