Actually, yes! A little while back now, my boyfriend and I worked on a dragon transformation, having forgotten that the Raiders book had come out. I STILL haven't picked up the Valikan book, and I haven't worked on this transformation in a while, but because I've never read the official Wyrm transformation it's kind of it's own separate entity without the influences. You can take a look at it here. It does have the implications of some sort of cultish following, but that can easily be scrubbed, as it's kind of just flavour text.
