Mehrunes' Razor is the fifth official add-on for The Elder Scrolls IV: Oblivion. It adds a fort called Sundercliff Watch to the game. Sundercliff Watch consists of nine larger areas (mostly dungeons) and various smaller ones. The add-on also adds a quest called Unearthing Mehrunes' Razor, where you have to retrieve a dagger underneath Sundercliff Watch, new items and characters.
