Kralkatorrik, also referred to as the Elder Crystal Dragon, is one of the slumbering Elder Dragons. It rests half-buried in the Charr Homelands, located in the center of the lake that separates the Grothmar Wardowns from the Dalada Uplands. Sediment build up has formed an island around the dormant creature.
The dragon went dormant in pre-historic era preceding the gods' arrival. Whether the lake formed after it went to sleep, was already present when it did so, or was formed by the dragon itself is unknown.
