Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Who is the last Origin character?

If this last character is to be some one we haven't met yet then where/how will they be slotted in to Act 1?

I'm still thinking about whether this character will have some entity behind them like the current 5 do. Karlach seems to be the opposite as she has 'rebelled' from her erstwhile boss (or so she says).
