A troll city that rose out of the sea. Cut from the original game, back in Forever.
Naga, makrura and risen trolls on an island no boat or flight path reaches yet. Very little is confirmed: this page is what we know so far, and it will grow.

Gillijim's Isle, southwest of Stranglethorn. The likely entrance is a blue portal in Sunken Hollow, a cave on the island. In the beta it didn't work yet, and no boat or flight path goes there yet.
Zone: Gillijim's Isle, off the coast of Stranglethorn Vale
This dungeon has no Classic version, so there are no old guides for it. What's here comes from the beta and the first weeks of Forever. Blizzard is still tuning it, so check your tooltips.
The dungeon counts toward the Legacy challenge Experienced Spelunker.
Bosses found in the game files so far (names and order may change)
| Mob | What to do |
|---|---|
| Makrura and crabs | First up after you enter. |
| Risen troll sentries | Next layer in. |
| Naga packs | Tight packs deeper in: Brinescale Priestess, Saltseer Manhunter and others. Crowd control helps. |
We'll update this page as soon as the dungeon opens and the fights are known.
With no boat, a Warlock who gets there first can summon the rest of the group.

Boss fights go smoother when you're not thinking about your rotation. Build one on the portal's Rotations page and Compass+ shows the next button to press, so you can watch the floor instead.
