I think the whole being TG'd into a dragon is an interesting plot development in of itself. The whole pregnancy thing I'm not 100% keen on, but the plot is well-written enough to let it slide. Plus, I suppose he'll only be pregnant for a few more months judging from the princess's belly. Or however long dragons are pregnant for. I can't see this being a focus in the far future.
That said, I'm really liking the comic so far and I hope Desmond and Jason continue it.
I believe the word you're looking for is Rite, which usually means some sort of ritual. Right of shadows kinda sounds like they're being given a right to have a shadow or something, heh ^_^; love the comic btw.
