Nul Doldum

The Black Fortress. Nul Doldum is assumed to be the twisted version of what was once the great capital of Men - Aethel Baelin. No living soul has seen the interior of this cursed place and lived to tell of it.
It is known that huge spears thrust into the ground with bodies pierced on them line miles of the surrounding land around the Black Fortress. Dark figures fly into the eternal night around Nul Doldum and Mount Peril. It is perhaps the most terrifying place known on Novaura.
Scouts have reported regiments of troops loyal to the Shadow go in and out with regularity but some seen coming out were never seen going in.
