Snowflake oozes inhabit the mountains and vales of the Mror Holds, northern Karrnath, and the northern mainland of the Lhazaar Principalities. Rumor has it that the lich queen’s blisteringly cold island called Farlnen (located in the Lhazaar Sea), plays host to several dozen of these creatures. Larger specimens prey on visitors to the Tashana Tundra (on Sarlona) and the Frostfell.
Farlnen is cold and bleak, with cliffs of basalt and beaches covered with black sand. When the elves came to the island, they found almost no vegetation; Farlnen is close to the plane of Mabar, and full sunlight never reaches its stony soil. The Grim Lord Varonaen overcame this challenge, and the fruits of his labors can be seen today: darkwood trees and ebon sedge grass that feed on shadows instead of sunlight. Varonaen has continued his work over the course of generations, and the merchants of Farlnen trade spices and wines that cannot be produced anywhere else in the world.
The waters around the island are just as dangerous as the stories say. Basalt columns and treacherous reefs pose inanimate threats to those who don’t know the coastline, and the undead sentinels pose an even greater threat. Anything that roamed the water over the centuries might have been slain at some point and bound to protect Farlnen. Krakens? Dragon turtles? Worse? It’s up to you to decide what lies hidden in the dark water.

Farlnen is blanketed in Mabaran manifest zones – even the brightest summer days only offer dim light. Combined with the life-leeching properties of Mabar, no plants naturally grow on Farlnen. Grim Lord Varonaen found a solution, magecrafting plants that would feed on shadows rather than light. In the millennia since Varonaen has continued his work, growing spices and wines found nowhere else in Eberron.
The Mabaran manifest zones are particularly fearsome in the winter months when the isle slips into perpetual darkness. While Port Cairn only experiences this perpetual darkness during Long Shadows over the winter solstice, the northernmost tip of the isle goes through nearly three months without a single drop of sunlight.
The lich known as Lady Illmarrow is one of the more active members of the Grim, funding and supporting the Order of the Emerald Claw’s terrorist operations in Karrnath. Reaching her fortress would be a truly epic task, as the already hostile environment is enhanced by powerful abjurations.
