Yes, Biara summoned hordes of demons to Ashan (before revealing her true form). I repeat, Kha-Belekh is in charge, and Biara is just a servant. And no one was fooled. The Overlord achieved his goal; he got his messiah. Instead of Isabel, he put Biara in her place. And in this way, he struck at the enemy's weak spot.
Charisma comes from fear... No, I don't know. In my opinion, charisma is when a person can motivate many people to take action because they believe in him, not because they are afraid. For example, Hitler was charismatic: he put forward an idea and preached it so well that all of Germany stood up for it. But, for example, Nicholas I was not. People obeyed both of them, but Nicholas I was an emperor with very strict military morals, whom they feared, and Hitler was an orator.
