I have installed the Immersive Creatures Mod.
After fighting a metal dragon I looted it and found "Strange Scrap Metal" which had "Blackreach" written on it.
I read in the discussion on that mod that this is a "quest" of some form in the mod, but they did not give any details.
I traveled back to blackreach and walked around a bit, but nothing happened.
What am I supposed to do?
