It's done! I wrote a quick little hack for "Agon" to play in a Norse flavor called "Ragonarok" (see what I did there?). The rules changes are available as text here on the blog or as part of a PDF that includes custom character and reference sheets, and a pretty neat little picture of Odin I whipped up. Let me know what you think! Even if you haven't played Agon, I'd love to hear what you think of the layout.
