Me would get angry at orc boss for thinking killing us gonna be so easy, but me spent from all the constant battling from the past day. Devil girl blow many of them up with her fireball, and then nature boy filled area with fog so pesky goblin archer can't shoot us. Shifty guy somehow close off passage behind us so we don't get pinched.
We hold line, and eventually kill them all, including big boss. Me chop of his head to try and cow the rest of his people. After fog lifts, we see remaining goblins gone. But they peek from around corner with white flag to surrender. We agree to let them leave city if they don't tell anyone about us down here.
Once they gone, we explore rest of complex. We learn more about orc boss. Apparently he a bandit leader named Norse the Grey who gathered half-orcs and goblins around him. He accidentally found secret complex after one of his men accidentally fell in well.
Too bad he threatened us, because it sound like he not truly allied with rest of monsters in city. We find out he was requested to actually join forces who came against us at keep, but refused because he know want to go against unknown enemy for vague promise of rewards.
We also find secret circular room in his chambers, containing mysterious archway. But we wait on investigating until we rest.
