I can't enter the Hill Giant's enclave (I'm blocked by a force field).
When I speak to the "Old Witch", she says that she hopes I'm able to free the hostages, or something to that effect.
However, I freed every hostage I could find.
I've been through the Orc fortress over and over, searching for a hostage I might have missed.
Also, in the original cave, I never got past some of the locked doors.
I sided with a dwarf who was opposing the king. However, he (the character with whom I had formed a pact) died during the fight with the king and his men.
I never found a key.
I sure hope that that doesn't prevent me from continuing (also, it doesn't explain why the Old Witch speaks as if I have not found all the hostages).
Any suggestions welcome.
