Mistmire Citadel
Once a mine used by Dwarves, Mistmire Citadel was refurbished by the lords of the Brierwell Estate, which supplied the estate with its considerable wealth. This led to the Citadel being converted into a makeshift prison, which provided forced labor for the mining operation there. For generations, it was utilized to quiet enemies and create wealth. That is until Niko Von Krohl seized control.
Currently, it serves as the Capital of Baron Niko Von Krohl’s mutant Iron empire. Krohl vents lethal Mystrium gan into the surrounding area, which has created a toxic blanket of protection. His mutant population is immune to the effects of said gas, due to many generations of mutations, and helps to spread his influence.
