Heimlyn Keep is a fortified settlement located in the region of Stonefalls, within the province of Morrowind. Heimlyn Keep is a settlement occupied by House Telvanni, where it is used to store objects with high-levels of magical potency, too dangerous to keep in circulation around the world. Those who administrate over Heimlyn Keep are highly-skilled in magic and knowledgeable in ancient magic. It has since been this way for many lifetimes.
In the First Era, two Chimeri mages that worshipped Namira had created a powerful weapon against the Dwemer called the Spellplague. But when it was revealed that the Spellplague was too powerful to be controlled, the Chimeri Lords had sealed both the plague and the two Mendicants into a vault, which would become Heimlyn Keep. The two were sealed ever since, falling into obscurity.
During the Interregnum in 2E 582, the town of Heimlyn Keep was invaded by the Daggerfall Covenant, who raided their settlement thinking it was a military target. But they had inadvertently tampered with the reliquary storing the magic, unleashing a curse upon Heimlyn Keep, the Spellplague. A wanderer had aided the Telvanni after the raid, eliminating the source of the plague. The vault was re-sealed and the people of Heimlyn Keep were saved from catastrophe.
