Thalassmortis, The Abyssal Glacier

Sailors whisper that Thalassmortis sleeps beneath the oldest glacier, dreaming of the sea it once ruled. When awoken, it rises as a walking iceberg, dragging ships, towns, and mountains into the abyss. It does not speak—it moans with the voice of collapsing icebergs and imploding caverns. Legends say Thalassmortis is the source of all frost undead, the first fisherman consumed by the sea’s hunger. Where it walks, time halts, and winter reigns eternal.
