Hell's Mouth Island

In the center of Tritonia is a small island. This island appears to be a separate hunk of rock sitting solidly atop a steep undersea mountain. Stone tendrils covered in thorns extrude from the mountain and wrap around the island, surrounding it in a cage of solid brambles that is open at the top. The surface of the island is flat and dusty.

Six obelisks sit on Hell's Mouth Island, each one tuned to a different region of the Inferno and connected to an identical obelisk within that region. When both obelisks are deactivated, the corresponding portal is locked and cannot open until both obelisks are activated again. While the obelisks are activated, either obelisk can be touched to open a portal between the center of the island and that region of hell.
