I've been lookin through the characters..
there's more then 4 isn't there?

1. Main Character
2. Yoshimo (Neutral)
3. Korgan
4. Haer'Dalis (Chaotic Neutral)
5. Edwin
6. Viconia

Now, Has anyone done the quest for our good o'l pal from BG1? Montaron and That Necromancer. They are Evil. Do they join your party or what?

The Quest would require a Evil Party...Breaking into the Harpers i don't think any of the good characters would agree with especially Jaheira.

The Kurgan...

Jan and Cernd are both neutral (chaotic & neutral respectively). Jan is a illusionist/thief and Cernd is a druid. I haven't done Xar's quest yet, but I know that you don't get Xar or Montaron in your party.
