Walkthrough for the "Tribes of the East" expansion.

Yesterday, I started playing the additional mission in Dark Messiah. It seems to be quite easy, as no one has asked for help with it. I couldn't find it among the single missions or the campaigns. Judging by the name, it is a continuation of the campaigns. Perhaps I will encounter some old acquaintances. My knight hero, a mage apprentice, mentioned Arantir in a negative way in the video. According to him, Arantir sends armies of necromancers against good people. He suspects that Arantir is the Dark Messiah. My knight has a suspicious mentor. He resembles Markel. And he also gave him a companion, Zana, who looks like Biara. I haven't had time to remember the characters' names yet.
