Jer 

Jer likes toes. Because of Jer, our group collected toes to give him. Probably why our name ended up being Toes Anonymous.

Thorin, Rei, and Esh met Jer before the Toes Anonymous moniker was adopted. Jer sold mostly potions. Like, pants-pooping potions.

Jer might have been an avatar of Greeba's deity. Or hell, might have just been her deity.
