On each of the continents of Mithrym, the Crafters made many creatures - both wild and tame - to suit their climate and to help or to hinder humanity in order to teach the Children of Een and help them grow.

In the earliest days of Mithrym, Immu created great beasts in the fashion and mannor of the dragons. Later, after the Children of Een were created but before Immu’s banishment to the Frozen Wastes, when humanity was still very young and primitive, Immu created beasts with which to task the young humans. While they are no longer seen in Mithrym, any whose journey might take them back in time has the chance of meeting some.
