I'm really impressed by how much thought has gone into all of your Greenwood Sword and Sorcery School characters and houses! Herne (Cernunius Hunter (clever!)) is the perfect choice for Headmaster! It ties in very nicely with the RoS universe and suits the world of Harry Potter as well. I think having Joshua de Talmont as an Astrology master and Head of Ravenquilt House is brilliant (given de Talmont's great intelligence and scholarly zeal), not to mention Robert de Rainault as your version of Snape!

I really, really want to read this story! :-D
