ToME: the Tales of Maj'Eyal

Would it be possible to implement some sort of pet shop? I think having a pet that can level with you and suffer perma death could be interesting option for some players. Maybe the summoner class can get additional advantage with the pets they can buy. Also maybe a slave market for those evil role players?

Currently there's a lot of debate over how much good items shops should sell, and I thought shops should offer something you can't find in the dungeon.
