Piety and Poison
After the Cairngorn Shadow Rift incident, a fortified keep was constructed over the closed rift in order to protect the magics that kept the rift closed. This keep came to be known as the Shadowfell Keep.
For over a century and a half, the keep stood over the rift with company of soldiers to defend it. With the Shadow Rift all little more than half-remembered history, the keep became known as a trade outpost and a point of refuge along the northern road.
Then one night, the keep’s overseer, Sir Keegan went insane and murdered his family and many of his officers. After this tragedy, many soldiers deserted the keep. Without support from the Empire, which was in the midst of the Nerathian Succession Wars, the keep was eventually abandoned. Within a century, the keep crumbled into ruins and came to be regarded with superstitous dread by the locals.
