I will definitely take an origin character.
At the moment the githyanki fighter would be my choice.
- You want to kill Illithids and that is exactly what gith do.
- She is not familiar with this place, this makes her a bit equal to the player (unless you are a DnD nerd)
- I guess most people do not know githyanki and those who do probably do not like then. They are evil followers of the lich queen.
- Probably make her an Eldritch Knight. In all DnD games (BG2, NWN2) all gith had arcane abilities, except the cleric companion of NWN2 (But with knowledge domain she had some mage spells too).
