ANCIENT STRUCTURE / MONSTERS w/ enchanted items
The travelers between Sweet Iron and Kynobirtheim always make sure to never look at or travel within sight of the Deadman's Tower after nightfall because it is said to mark the person for death.
The Zaybirilfin's special knowledge is how to cloak themselves and communicate with the draugr in the Deadman's Tower and will use that information to disguise themselves as undead raiders coming and going from the tower.
The soldiers of the Vurbiogihin will often haze new members into kissing a specific stone at the base of the tower. It is also a common punishment inflicted by superiors.
The Redcap Stabbings are the responsible for the Deadman's Tower being awake and actively keep them awake.
