The Iizbord Vasik, known as the Ice Drain, is a river originating from the eastern glacial slopes of the God Rim. Except for seasonal flooding, it is a slow, meandering river that flows eastward through canyons inhabited by basilisks, ambush drakes, cave trolls, and other creatures. Emerging from the God Rim, the river takes a southerly course through a region of sky islands, the so-called Lifted Land. Continuing southward, the river enters a wide valley flanked by peaks and dotted with wetlands. After traversing the Thongath jungle, the Ice Drain ultimately reaches the Morwuld Briin sea.
