Aknimchuk is the largest island at the far north of the Northern Isles, and the only one that holds any warmth at all. Volcanic fire heats its southern half. The rest is ice. No one lives here. The island is too far north to farm and too violent underfoot to rest on, and the handful who tried to stay are remembered, if at all, as a warning told in southern harbors.
The two halves
Aknimchuk runs roughly two hundred miles north to south. The Passage of Hagol separates it from the mainland to the west; open water lies east. Its southern half belongs to the Ashy Mountains, an active volcanic range whose heat is the only such warmth for hundreds of miles. Beyond the mountains' reach the land becomes Scheyolonae, tundra and ice as brutal as anywhere else this far up the archipelago. A traveler walking north feels the change inside a single day's march: steam and warm stone behind, killing cold ahead.
Strange waters, stranger fauna
The volcanic ground does not make Aknimchuk hospitable. It makes it strange. Vents, hot springs, and pockets of buried heat sustain creatures that live nowhere else and tolerate nothing milder. Ice salamanders the size of hounds den in the caves of northern Scheyolonae and hunt in packs. Things adapted to ash and sulfur hold the southern slopes. In central Scheyolonae the Iceburn Lakes never fully freeze, and their water scalds and freezes the skin at the same touch, faintly luminous on dark nights and prized by the few alchemists who can get a flask of it south. Between the fire and the ice there is little a person could eat, and a great deal that would happily eat a person.
Smokey Bay
The one shelter on Aknimchuk is Smokey Bay, a southern inlet warmed by vents in the seafloor until ice never closes over it. It is the only water in the Northern Isles where a hull is safe from the pack. Ships with business this far north, and very few have any, ride out weather here. None of them stay. There is no town on the bay, no dock, no one to trade with: black sand, warm water, and the reek of sulfur, and then the open archipelago beyond.
The Tomb of Angi
The single mark of anyone's hand on the island is the Tomb of Angi, cut into a dormant peak in the Ashy Mountains. The fire mage who chose Aknimchuk for her grave left it guarded, and it has stayed sealed against every expedition since. Whatever the island was to her, she kept nothing else of her people here. The tomb endures; the people did not.
