Where is the "none" option?

The implementation of classes is a bit unfinished at the moment, both the UI and the mechanics is hopefully going to see major revisions.

The story is kinda fun with a goodish drow PC and perhaps a tiefling, but that is very class unrelated.

The Chapter 1 does come with a nature wibe, so ranger and druid does seem to get the lion share of motivational gameplay, where the rest is a toss up between being a murderhobo or a being a hero because you are a hero. It makes no difference what a fighter does, either kill them all or not, all roads lead to Baldur's Gate equally.

You can kill all the tieflings, druids and goblins and get to Baldur's Gate.... Only thing you can't kill is Gale.
