Hey, everybody, I'm here again. I'm very much afraid of spoilers. Without spoilers, is there anything I can do with the Karlach engine?
Hey! Phrasing it as non-spoilery as I can: you, the player, in the game - no, but there's now a much stronger implication that the characters, eventually, might well be able to.
Whether that's just an optimistic open ending or a hint at any continuation is up for theorizing.
