It seems like the last origin will be a Dragonborn Sorcerer serial killer, really disguisted with how edge lord Larian has been with the origin characters. Folks begged for a good origin character, Larian heard serial killer some how. So very angry right now.
If this dragonborn is the other origin character, they are probably a good character who is brainwashed/manipulated by the goblin, following the pattern of all of the origin characters having something controlling/influencing them:
Shadowheart - Shar (there are several scenes that imply that Shadowheart is/was actually a brainwashed cleric of Selune)
Wyll - Minthara
Gale - Mystra
Lae'zel - V'laakith
Astarion - Cazador
Dragonborn sorcerer - creepy goblin?
Karlach - Zariel
I'm not bothered in any case because I've already pretty much decided that my party will be a bard Tav with Shadowheart, Wyll, and Karlach. A dragonborn sorcerer doesn't force me to re-think that.
I AM surprised that the game apparently has zero joinable dwarves, halflings, or gnomes.
The game doesn't actually have alignment, but even if it did, I'd say the origin characters represent a pretty even spread. I'd have Wyll, Gale, and Karlach down as good (Wyll probably chaotic good, Gale as neutral or lawful good, Karlach tbd). Lae'zel as lawful evil, Astarian as probably neutral evil. Shadowheart is a wildcard because she is possibly brainwashed, so I'll call her neutral for now. If the dragonborn is evil, that pretty much makes three evil and three good origins, plus whatever Shadowheart is. I also suspect that Lae'zel and Astarion, while evil, are probably both morally redeemable in the full game for players who have the patience for them.
Then for non-origin joinable characters, we have three good ones and one evil.
So on the whole, more good options than evil ones.
