Aasen (sg. Aase)[]
The Aasen on Myra (English description with picture) are native in the other half of the world, beyond the Bloody Belt of volcanoes, the Ophisworld where women rule over men and witches over amazons, but a few of these green-skinned little (2-3 feet high, plus their phyrian caps) humanoids could be found so close to the border to the Ophis. Witches use those Aasen who are not magic-users as magical mediums and conduits to their own power.
