[@Lucius Cypher] It's described in the commoner class we're using. There's a link to it in the opening post. Again, too lazy to get it.

Basically, we go through 5(kind of) levels of commoner, gaining small bonuses per level. The bonus for level 5 is you remake the character using the normal rules, with a standard class. If you pick the same starting class as the one you picked for your commoner level 2 ability, you get a bonus starting level. You also get a bonus feat.

I've got no idea how it will all work in practice, but eventually, you should(could) end up with a traditional character. No idea how it's all going to stack with existing traits/abilities/feats/etc. However, given the nature of the game, it's a toss up whether it's going to end up mattering at all.
