She is a typical Middle Earth female elf, good with the bow and arrow and the ability to use magick. She also has a magickal dagger which she keeps at hand. Eirianna gets her magickal strength from the moon: the closer to full the moon is, the stronger she becomes and the stronger spells she can cast. Likewise, the more the moon wanes the more her powers lessen until at New Moon she is unable to use magicks at all.

He bears her upon his back the few times she travels beyond Moon's Keep, but otherwise runs wild and free in Wydde's Woods.

Here is her wood's wraith, Hecate:
