Alright, thanks everyone I'm actually pretty much the GM in this case, these are potential NPCs in what is probably going to be a single player campaign. Just wanted to get some opinions before I decide if I want to make him a Paladin or a Dragon Slayer Ranger.
Now, something else I just thought of... what if he had eldritch heritage Silver Draconic? Would that negate him from being able to be a Wyrm Paladin, or would it just mean he doesn't LIKE his family (and would be not having kids more than likely, unless he only hated evil dragons), kind of like a tiefling paladin taking Oath against fiends?
Haha just had a funny thought... at level 20+... Raid on Hermea! Cause JJ pretty much said, if they stated out Mengkare, he'd be a LE Gold Dragon, not the usual LG.
