Ahtohallan

Ahtohallan is an ancient river that appears in Frozen II. Described as a river “full of memories”, Ahtohallan holds all the answers to the past. The river is a prominent part of Northuldran culture, who sing about Ahtohallan in their lullaby “All Is Found”. Though widely thought to be mere myth, Ahtohallan is real and takes the form of a glacier (which, in laymen’s terms, is a river of ice).

Background
Ahtohallan is located on the Dark Sea. It acts as something of a visual archive. By projecting scenes from history along its icy walls, Ahtohallan allows its visitors to learn all there is to know about their past, and the people connected to them. However, traversing Ahtohallan‘s caverns can be extremely treacherous. As “All Is Found” warns, those who go too deep into Ahtohallan will “drown” (in reality, freeze to death).

Trivia

 * Ahtohallan has a special connection with the spirits of the Enchanted Forest. While Elsa and Bruni were able to hear Ahtohallan‘s calls, others like Anna and Kai were not.
