Kolning is a volatile island situated off the southeastern tip of Gorejun. The majority of the island is blanketed in deep black volcanic ash, with numerous burning peaks dotting the landscape. At least one volcano is perpetually erupting, while the others send plumes of smoke far out to sea or, when the wind shifts, engulf parts of Sirketh's interior. The volatility of this region is unnatural, a consequence of the opening and closing of inter-system Rifts, each serving as a conduit for the lava and pressure emanating from the distant world of Muspelheim.
Kolning's interior is ever-evolving, punctuated by chasms and rugged plateaus, collapsed volcanoes, and smoldering fissures. It is said that Kossuth himself orchestrates this perpetual transformation, alongside his devoted workers, striving to contain breaches that even the Web's indefatigable spiders cannot mend.
Kolning is the abode of numerous fire-dwelling entities, with Azer, salamanders, and firenewts being the most prevalent.
Vast mineral wealth is rumored to exist on the island. The majority of trade with visitors is handled by the azer. They import wheat, fruit, and other foodstuffs that do not fare well in the island's frequent volcanic eruptions. In exchange, ships depart with gemstones, finished goods, iron, silver, and platinum.
