It's probably way to late for this, art's probably all done and everything but... I hope the auction house isn't going to be actually named 'auction house'. That doesn't fit the theme of spiral knights very well. Fitting the military theme, it could be the PX ... Post Exchange in RL, or if it's actually named 'PX' in game, players can decide for themselves if it stands for 'post exchange' or 'player exchange'. Or it could be 'Supply Depot' mirroring 'Energy Depot'. Or many things. Just not auction house, that sounds exactly like it was taken from a game with a different theme. ;o
