Karst lived in the Nora settlement of Mother's Heart until he was cast out from the tribe by the High Matriarchs after he was caught exploring the forbidden metal ruins in the Sacred Lands. He was sentenced to a five year term. When his shunning was finished, he returned to Mother's Heart and discovered that his old friends had moved.
Karst therefore decided to make a home for himself in the wilds of the Embrace, returning to the life he had grown accustomed to during his time as an outcast.
- Karst's House is a location for one of the Grazer-shaped training dummies that must be destroyed to obtain the "Downed 23 Grazer dummies" trophy.
