The Knahaten Plague

The Knahaten Plague was a virus that spread throughout the entirety of the Kingdom of Skyrim, killing millions of commoners and nobles alike. Originating in Argonia, through means unknown the plague was transferred to Skyrim. Countless Barons, Counts and even Kings were killed, bringing the Kingdom into a state of utter turmoil and civil war.

The Fairhair Dynasty, once mighty and proud, was destroyed by the plague with all of its members either dead or overthrown. Countless landholders were killed along with their entire familes, leaving many titles without heirs. The plague was and still is the largest event of mass-death in Tamriel's history.
