Enchantresses are not unalike . They live for centuries, cast poem-like spells, have magical blood, and even call on the same powers as wizards.
Rhia, the lady of the lake is one example. The giant who tried to kiss Shim after he saved her, and her mother, is another example. Some belive that an enchantress is merely a female wizard. So disagree, due to the fact that it is mentioned that there is wizard, and enchanter. Er. This may mean that the female wizard has another name, perhaps a wizardess, and an enchanter is a simallier, though slightly different path of magic, but then again Rhia became an enchantress, so it is possibly that if the Eopia family has no other magical heritage then this is merely the female variation of a wizard.
