Devil's Rift

Located east of Chalisar, the Devil's Rift is a very dangerous sea. Centuries ago the entire area was above water, but due to the deployment of multiple cataclysm scrolls the land began to crumble, and fall into the sea. One of the scrolls deployed seems to have brought forth a massive, un-dispellable gate that reaches deep into the hells. As the land fell into the ocean, the gate remained.

It took years for the devils to make a beachhead this side of the rift, and initial fleets that sailed out to drive the infernal creatures back trough the rift were successful. But Fleets take time to repair and while the ships were back in port, the devils were fortifying the rift. The Floating Citadel is a marvel of Infernal engineering and had rendered the Rift it's self unassailable. A massive floating defensive installation now protects the rift and lets the devils launch their own ships into the sea to go and raid the surrounding area.
