Lake Arrius is a lake north of Cheydinhal. It can be found right where the Nibenay Basin region meets the Jerall Mountains. A small community of worshippers lives around a shrine to Azura northwest of the lake.
In the Second Era, it was the site of Arrius Keep, a fort in the center of the Ebonheart Pact's claimed territory. In 3E 433, the Hero of Kvatch famously infiltrated a Mythic Dawn lair near the lake and took the Mysterium Xarxes as part of the effort to end the Oblivion Crisis.
- Though Modern Heretics says the shrine to Azura is northwest of the lake, in TES IV: Oblivion, the shrine is almost directly north of the lake.
