Yes, I hadn't forgotten but it was pushed back farther in my mind. In terms of story line, the party hasn't been that pressed by Nisha lately. Maybe it's because the Old Man has been avoiding them. Maybe it's the bugbears and the goblins not avoiding them. Maybe it's the excitement of getting past the locked door and finding so much inside the catacombs. At some point I'm sure he'll inject himself into my life again.
But there's a lot of ways it can go, which means... wing it!
Here's one fun scenario.
Old Man meets the party for the first time. [sinister voice] "So, we finally meet. Too bad it means your demise."
[Tiana] "Not so fast. I too have mastered the powers of the Salen." (insert hordes of iron golems/zombies/whatever here)
[Kilian] "Don't be too proud of this magical terror you've constructed. The ability to destroy a human is insignificant next to the power of the RockFather." (summons hordes of stone golems)
