Very little is known about the Crow Clan. They are first seen by Mercy when she infiltrated Dalborg, serving under an unnamed Viking clan. A Warborn Viking was bragging to the Crow Viking how the Warborn could unite all the Viking clans if they ever desired.
After the destruction of Gränsgård, the Crows starved like the other Vikings. It is unknown if they were ultimately destroyed or swore fidelity to the Warborn.
