Description
A cavern of blue-white ice in the frozen north, where the portal in Seylon's Tower comes out. Frost lies over everything thick as glass and there is no way onward but to break through the wall.
Deeper in, a vast spiralling chamber ribbed with ice, webbed between the stalactites, with a mound of half-frozen bones at its centre. The party came through here in Session 7 - Through Portals and Ice and fought the Ice Widow that nests in it.
