Wow I don't look for a day and the thread explodes.
So what is a dracon? No one explained.
It varies a lot as there are many interpretations, but look at my avatar. That would be one example of a dracon. In my experience it is a roughly human sized humanoid with dragon features. Distinct from dragons by their size and humanoid shape. And usually a species instead of being the result of a 'dragon X something else' pairing. There have been more than a couple mods that include them, and at least two where they are the primary focus.
Half Breeds, epic.
Could use castes to give them a variable amount of dragon blood (some have wings, some don't, some pass for human, some look fully dragon)or make the mixed races. (Half-human, half-elf, half-dwarf, half-kobold, half goblin...) Or hell, a creature can have some absurdly high memory friendly number of castes, why not both? Though they would be able to create any of the castes breeding, no way to control that, so it might be odd to see two half-dragonelves make a half-dragonbold.
@clothes
Might be able to make some custom clothing items that are basically just like decorative items and have the game treat them as clothes with a very low coverage value. Like a decorative collar or chain that has a very low coverage, to not provide any real protection except for the off chance an attacker hits the chain itself. And give it the clothing tags neccesary for the game to read it as torso clothing. Add similar things for the other bodyparts that require clothing like lower body and claws and maybe a custom reaction to make them. Might even give a real reason to use gold silver and gems, by making them require small amounts of those materiels to be made, dragons love their bling.
Traders and migrants would probably come with cloth ones, but replacements need to be made of precious metals.
