The Fissure of Oblivion is a (timed) solo instance for Archdaeva players of level 66 or above, introduced in the 5.1 update. Entrance is gained via interacting with the Rift of Oblivion found at the Kojol Valley Scout Post in Iluma (Elyos) or the Nightbloom Forest Scout Post in Norsvold (Asmodians). Ever since its release it has been hailed as one of the best (current) sources for experience in the game, making it an incredibly popular dungeon among players.
