@millyk - Haven't seen you about for a week or so, everything OK?
For the rest, I will need you to make a group decision (or someone make a decision for the group) as to your plan. Lurzook will not make the decision for you.
The way I see it you have a few choices:
1) Set up a fake camp, and try to "reverse ambush" them when the orcs come at night.
2) Observe the orcs from the goblin's suggested location and then do... something (follow them, attack them, whatever)
3) Tell Lurzook you'll handle it and then just leave.
4) Continue hunting the orcs in the daylight.
Things you've been told or assume about these orcs based on conversations so far:
-> They can see in the dark and use that to their advantage
-> Their leader is brutal but the spellcaster with him is worse
-> They have 6-8 orcs that you'll have to deal with.
Once someone from the group makes a decision for which way you're intending on advancing, I'll push the story forward.
