In OTL, the worldwide Norse conversion to Christianity followed the Norse colonists to Greenland by sixteen years, resulting in the conversion of the colony in about 1000 CE. Clinging to their identity as European Christians, and their lifeline to Europe, contributed significantly to the failure of the colony. Also, Eiríkur Rauði (Erik the Red, hereafter Eirikur) and his colonists apparently had some irrational phobia of fish-eating, which also contributed to the failure of the colony.
