I've been looking for Nibelungenlied fanfictions for AGES and this is just lovely. *squeals in delight* Hagen is my favorite character and I just love the way you write his POV, I think it's really quite IC and the line about boudoirs and fire-hazards cracked me up! Also, Vorkel and Patavrid are adorable. I really can't say much about the Parzifal characters as, well, I've never read Parzifal and I know about it only thanks to the Internet and a couple of lines in Once And Future King, but I enjoyed the unearthly atmosphere and now I'm quite interested in knowing more about Antfortas.
All in all, one of the most enjoyable crackfics I've ever read. :)
