Leave Zalyn to the south and a Tizmak Hero (level 90^) will attack you. Once he reaches 50% health, he changes into Toridar Mudhoof, then you can talk to him.
At 50% health you can speak to Toridar. Be careful of your dialogue choices. The correct responses are:
"I was tricked! Betrayed by a fellow adventurer that used my compassion against me!"
"It made sense at the time. Is there anyway I can prove to you that I mean no harm to the Tizmak?"
"Yes, I'll go free them at once!"
Note: 1 one Tizmak Hero spawns for each group member
