Do we have a light source, and if yes, who carries it, and what is its radius? Schnickschnack does not need one while exploring, but others probably would. I think it would be best not to give us away by our light source, if possible.
Schnickschnack should be in the middle of the party, he is obviously not a melee combatant (he'll use his knowledge, his spells and his hand crossbow in battle), and I also suggest that someone else goes first, as the orc might trigger traps.
Suggestion:
1) Someone able to scout (Earmy or Eliath -- not sure whether they need a light source and if we can have someone cast darkvision, if needed)
2) Orc
3) Schnickschnack (if there is a light source at the front, Schnickschnack would want to switch places with Emagor -- if not, going at position 3 is fine)
4) Emagor
5) Eldwyn
6) Earmy or Eliath
Edit: just saw the orc's reply in the IC
