Cubewrack is a vast area of arcane concentration that spans the entire eastern coastline of Ice Cap. It is where magical energies from the Cube of Arcane transform ocean water and moisture into a glacial flow that extends eastward, from Sirknarri, across Kindarum and Fjorvir, and into Aettein.
Cubewrack is blanketed with intense blue-white ice. The concentration of ice is greater here than in other areas of Ice Cap. The region also features deep, eerie glowing crevasses. The arcane emanations permeating these areas provide a boon for anyone utilizing arcane magic in the vicinity. This grants the caster the effects of both a Zone of Great Magic and Extended Duration. The boundaries of Cubewrack fluctuate westward between twenty and one hundred miles at any given moment, with no defined area. This region hums with potent magical energy, strong enough to disrupt magical holds, charms, paralysis, prisons, and similar effects as if dispelled by a level 25 caster. This is a continuous phenomenon. Some have leveraged this to free comrades from such enchantments or release captives from bottles of entrapment and other magical prisons. However, those who have ventured here warn that it is extremely perilous to transport items containing extra-dimensional spaces, as they are often ruptured by the Cube's energies, resulting in a magical whirlpool that draws the feeble into the Web of Magic, where they are lost forever - unless they possess the means of teleportation.
