Here's a forecast on the mentors devastating attack against a defector hideout.
The mentor is a mysterious ancestor, who already witnessed an occurring of the Big Five a long time ago.
He does not know anything about that time period besides the fact that the Big Five secured the balance.
At first glance the mentor appears forgetfully but clever. He almost moves in slow-motion, but shoos wild beasts away with just a tiny hand gesture.
Our heros, Chipo(18) and Bokar(18), first meet him after a ceremony at the scaffold outside the castle.
They quickly experience that one couldn't judge power by appearance only.
