Last week I discovered a Korean 'Crow' too in the kids section of my local library:
The Crow King in the story - a ogre-like character with hundreds of smaller crow familiars who is beaten by a brave boy in the Underworld - was quite different from what I've read about the majestic Korean Samjok-o, a symbol of power to beat dragons and phoenixes. Are there stories about him? Hopefully I'll find out this week at Storytelling School, where I will live either in the classroom, or the library, for the WHOLE TIME. I can't wait. Only a few hours to go!
