The Abyssal Depths, unlike Vashj'ir's other subzones, has wildly varying topography and geography. Players will be very familiar with the deep caves of Darkbreak Cove and Tenebrous Cavern, similar to the faction hubs within the Shimmering Expanse. Outside these caves, the world is full of multi-level coral reefs and tall stone pillars. Slicing through the south-central part of the zone is a deep, dark trench, full of giant eels and deep sea murlocs. This canyon rests beside the ancient L'ghorek, an entity related to Nespirah. To the south of L'ghorek is an abandoned reef, full of grey sands and murky waters, with only skeletal fish floating through it. The central part of the zone hosts steaming hot thermal vents jutting form the brownish, burnt sands. The most notable feature is to the northeast, where the immense Abyssal Breach lays, a deep chasm punched into the depths with a constant vortex pulling all things into its center.
Players begin their excursion within the Depths by attempting to discover a viable alternative for submarine fuel, and this rapidly evolves into helping hide their faction's secret submarines from the other faction. Quests bring players into the luminescent Underlight Canyon, there to assist a swimming-challenged dwarf or a forlorn orc who is looking to avenge the loss of his wolf companion (don't worry, she's okay!). Emerging from the dark canyon will bring players to fighting naga, repelling Faceless ones defiling the local fauna, and assisting the ancient, L'ghorek. This all culminates in a final battle against the naga at the Abyssal Breach.
