Most teens get banned from the Xbox Live servers for sending abusing messages about another's mother or whatever. Erika has a far more interesting way of getting banned from Halo!
Joking aside, do ring worlds exist in the Araltys' galaxy? Probably! Not under any kind of natural cause, but I could see Araltians creating unusual worlds just because they can.
I really need to draw more of Erika just having fun. It's what she does best. And this is a fun idea for a ring world that avoids the clichés of well, "ring" ring-worlds.
