I’m not sure if you’ll get yelled at for spam since I have a thread going but technically mine has been mostly about them becoming an Allied Race. However I think if they do it well, customization would be pretty neat. So I’ll leave my idea here for it:
This way we get lore tidbits without dedicating a huge questline that would get people to complain. It’d answer some questions that are holes in lore too.
Finally, this concept of short unlockable customizations, just some quests for flavor lore, could apply to many things people would enjoy.
