The first IC (and OOC, if i remeber right) post has a list of locations. Post in any of these and pick a fight with whoever's free. Though it's going to be hard, since the only other tier 3 character is already occupied in a fight, and Schradinger's adjustable tier robot hasn't been construced yet.

Though i guess the arena's reality warping may solve that if having a character fight two fights at once is allowed.
