Yeah Caelar is essentially a horrible person. Like the most horrible person ever. Sarevok at least wanted to orchestrate a glorious slaughter so he can become a god. She lead countless people to their deaths and driven even more from their homes just to free her fucking uncle, undermining his heroic sacrifice in the process. What the fuck. It's not like he was being raped by some cock demons. Belhifet was such a bro he just kept him in a cage, probably discussed his plans of conquering Icewind Dale with him (I assume this game happens before, since he says it was forever since he walked the Prime).
What makes the whole thing even funnier is that the whole crusade and raising an army wasn't even needed. At the end of the day the player and his party free Caelar's uncle basically on their own
. So all she had to do was ask him nicely to solve her problems, like he did for countless other people before.
Also, the crusade and siege was pointless filler. It is completely unreleted to anything in original games and linking of BG1 and 2 happens in the last 15 minutes and is so dumb I almost turned to into a Slayer while watching it.
It also creates plotholes. Like if CHARNAME is a hero of Baldur's Gate and Dragonspear, you would assume he was kinda famous. In fact, it it flat out shown that half of the BG city adores him. Being accused of murder doesn't make everybody stop talking about him, it makes him even more famous/infamous. Meanwhile in BG2 in Amn, which is a neighbouring nation, nobody recognizes you and you can't tell anyone how famous you are. This wasn't a problem before, because BG2 intro doesn't state that you were recognized as some public hero. In fact, it implies otherwise.
Also I loled about that "We decided to get rid of you quietly so get out". That's not how you get rid of somebody quietly. The public is gonna question wtf happened with that guy. And if you say he escaped, they will be angry about letting out a potential monster into the wild. Who says he won't come back to BG to enact his vengeance? Getting rid of somebody quietly is an euphemism for murdering them in thier sleep.
