Cormyr Forgotten Realms Game

[stupnick]

Stopping outside of the area a little ways, you are easily able to get w/in the 640ft, w/o being seen, now whether they patrol this area or not, you do not know.

Edit:
Spending almost 22 minutes casting the spell an in trance during the spell, you don't seem to run into any problems. No orcs wander by. No one else bothers you.

What you are able to see in, is just about 10-15 ft as darkness envelopes the area further in. What you are able to see if just cave walls, watching there for the 12 minutes, you do see an orc walk into the cave, and then after about 3 minutes he walks back out with a carcass of a squirrel on a spig. From there he walks over to the fire and begins roasting it. No other activity is noticed. You are able to tell the cave is just naturally dark, not magically, as when he was walking in, his faint outline was still there for another 5-10 ft.
