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.
