Kolning is a volatile island off Gorejun's southeastern tip. Most of it is covered in deep black volcanic ash and dotted with burning peaks. There is always at least one volcano erupting. The others send plumes of smoke far out to sea or when the wind changes, blanketing parts of Sirketh's interior. The volatility of the area is unnatural, a product of inter-system rifts opening and closing, each serving as an outlet for lava and pressure from the faraway world Muspelheim.
Kolning's interior is ever-changing, broken by chasms and jagged plateaus, collapsed volcanoes, and smoking fissures. It is said that Kossuth himself is behind all of this, he and his workers doing their best to contain the rifts, tears that even the Web's indefatigable spiders cannot keep closed.
Vast mineral wealth is rumored to exist on the island. Most of the trade with visitors is handled by the azer. They import wheat, fruit, and other foodstuffs that don't fair to dwell with the island's frequent volcanic eruptions. In exchange, ships leave with gemstones, finished goods, iron, silver, and platinum.
