I've played D&D tabletop a long time ago and spent thousands of hours on the BG saga, but I've never been a pro in the alignment system. I have some doubts about the alignment of certain companions. Any thoughts on the matter?
Neera: chaotic neutral
I get the feeling she's only CN because she is a wild mage. When you do her BG2 questline, I think she comes over as more CG, however. She goes through incredible lengths to save wild mages and her banter isn't exactly CN. Granted, she wants to kill every red wizard she sees, but that doesn't really CN to me. After all, the red wizards are friggin sadists who experiment on her kind.
Edwin: lawful evil
Edwin is a red wizard and therefore part of an evil organization with many rules and codes. So LE, right? But from the things he does and the way he acts, he's more NE to me. He's incredibly selfish and power-hungry.
Jaheira: true neutral
Jaheira is a druid and a harper, so by definition TN. Balance and shit. In the game however, she seems more NG. She's understanding, has a disgust for corruption and evil. She doesn't get along with any evil characters, but seems to fit in perfectly with a good-aligned party. Her late husband was NG.
Dorn: neutral evil
He actually lives for violence and slaughter, so shouldn't he be CE? Then again, in BG1 he lives according to the code of his patron and should be LE?
Korgan: chaotic evil
While it's true that he loves violence and murdering people, he's also a mercenary and will join good-aligned parties if the price is right. Isn't that NE? The man's actual last name is Bloodaxe, though, so CE would be fitting for that
Faldorn: true neutral
How in the Nine Hells can anyone call Faldorn true neutral? Shadow Druids are not about balance at all. In BG1 she's already an extremist and in BG2 she becomes a terrorist, wasting animal lives in futile attacks on the evil civilization that is Trademeet. She 'becomes stronger than ever' and willingly throws away human and animal lives to reach her goal. That goal seems to be power to be in stead of balance between civilization and nature. So NE?
