[@Kronshi] I actually had several homeworld gems in mind from that RP I tried to make.  I don't know if I'll submit (Edit: one of) them, but maybe?  Confession time: Spinel was actually originally going to be a homeworld gem in an RP that never got of the ground, so any other gem I would hypothetically submit would be written about as well as she is.  (But probably sans the 'Nope I'm out' moments for Bloodstone's sake, as amusing as that would be.)
