This is Agatha.
~senlienz told me something about her, because I didīnt know much about them:
They're Valkyries. But they serve more than one purpose in warcraft, it seems.
They're meant to pick who lives and dies in battle and take half those souls to prepare for Ragnarok, leaving the toher half for Freyja.
In warcraft, they seem to be heralds of war and some seem to be serving the Banshee Queen, for reasons I've forgotten...
Thank you again to telling men this!
I hope you like it
