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

Where did he get the whole kingdom? As far as I remember, the campaign with him ends with him simply leaving, saying that now people will manage without him. Like, the Moor has done his job, the Moor can leave. The game ends with the empire being passed on to Friede and Duncan, and Arantir is nowhere to be found.

What do the Griffin Empire and the Necromancer kingdom of Erathia have to do with it? Before fighting the demons, Arantir united all the necromancers under his rule, and he destroyed those who tried to resist him (like Giovanni). That is, Arantir became the supreme ruler of Erathia, which was destroyed by a coalition of humans, knights, and elves. In the same way, Raialg (uniting the dark elves) and Wulfstren (subjugating the dwarves) acted in their time.
