Tenebrous Cavern

The Tenebrous Cavern is a massive cavern located in eastern Abyssal Depths. This cavern was used as a lair (according to the Horde storyline) by Ozumat until the Horde, using the Verne, forced the creature to leave. The Horde then proceeded to set up a large base camp inside.

The cave entrance is right next to the Lightless Reaches that wraps around the Shimmering Expanse.

• After the events of the final quest in the zone, Defending the Rift, all the NPCs remain interactable and do not phase out.
• Unlike the other underwater caverns throughout Vashj'ir, players cannot fly in this one.
