In your opinion, which hero has the most charisma in the campaign?

If you want to know about Executor, I had the same problem as you. Check your computer for viruses or reinstall the game. As for the video, it plays after defeating Kha-Beleth. Kha-Beleth teleports off the battlefield, and Isabelle, supposedly healed, returns to the ruined place where she was married to Nicholas. She talks with Godric about what still needs to be done: "new monks, inquisitors, and so on." Her eyes sparkle with fire, and that's the end of the video. The story of the real Isabelle and Railag will be told in the first add-on, in the third campaign, in the third mission. According to the script of the first add-on, Faydaen returns to his homeland (find out what happened to him there) (nothing more is said about him in the fifth game). Zehir also appears in the script of the first add-on; look for him and play through it (the scenario is called "Temptation"). Zehir also appears in the second add-on, in the third campaign; play through it and find out. At the end of the trilogy, in the fifth game, he will also be there. So, watch and play through it, and see for yourself.
