Ah, I see. The funny thing is, Kullermes (IIRC) seemed to be the "bad guy" of the story, yet you wrote Rapture, represented by Kullermes. Heh.

The reason why I thought O-Thorde could've been Mephi is that Kullermes was talking about how "Rapture's coming." After all, O-Thorde was coming up his mountain. I also suppose the idea of Kullermes writing on leaves (or paper, for us modern folk) makes more sense now, since Rapture got published.
