I’m going to make a guild just so I can get a Guild Bank (yeah, I keep a lot of crap, but at least a couple people have been thankful for all those low level mats). Trying to think of a good name. Ideas:

Celestial Knights
Antimatter
Azurra
Aurora Borealis
Blazar
Culmination
Coronal Mass
Critical Density
Dark Matter
