Ring of Fire Island Chain

Just south of the Tarnished Coast lies the volcanic islands that together make up the Ring of Fire. The large volcano at the center of the ring is where the gods reportedly dropped the Bloodstones before leaving Tyria for good. Of the islands that surround this one, many are still active. Ships that pass by the Ring report hearing the tell-tale hiss of scalding hot lava hitting the ocean, instantly vaporizing the saltwater into steam.

The reefs off the islands are formed of black pumice stone. There are very few natural ports, and those suitable for docking put the crew in danger of being caught by a sudden, unexpected eruption.

There are no known settlements on the Ring of Fire.
