The Brass Keep

[Nirnaeth Arnoediad]

Hi there!

Could someone explain me why when I capture Brass Keep I can repair only one of the three unique buildings within (Brass Keep-Great Observatery-Ancient Reliquery) ?

Because those buildings belong to a different faction. i.e. unique to rebels. Only structures built by a culture can be repaired by a culture.

The keep itself is a castle which can be repaired by any culture

In my personal change i give this fortress to Sylvania faction and add a graveyard, like this undead can be recruit but if Empire hold the Keep they cant recruit troop Muahahahaha!
