Hello there.
Recently I have been wondering how, or if at all, the Khutit form makes sense for a Lunus dragon. They see bipeds as lesser beings, so what could possibly make them assume a form similar to them?
How about introducing a second alternate form only for the Lunus faction, leaving the Khutit form for Helians. If a Lunus would even bother to enter biped buildings, then I think he would do so without leaving his draconic shape, if anything just size it down.
Right now I am simply using a 'mod' that lets me see Khutit dragons as hatchlings and I very much prefer that to walking around as weird (and finless!) wannabe sslik.
