TzHaar-Mej-Kah is the proprietor of the TzHaar Fight Pits. He will guide you through the Tzhaar Fight Pits minigame if you talk to him. If you happen to stay long enough, it will say he has grown impatient and you will start getting hit 10's. While TzHaar-Mej-Kah seems to just be a really old Tzhaar, he is actually one of the oldest Tzhaars in the city.
