This may have been discussed before but your earlier post made me wonder; if keyleth WAS a dragon what kind would she be? I would be inclined to think either brass or silver. brass because they treasure conversations and story, and one day stories will be all that she has left of her friends; or silver because they tend to find value in relics or old civilizations, which i feel keyleth would have personal connection to as she grows older - anything to help remind her of earlier times.
I’m not super up to date on my dragon lore but personally I’d say silver. They’ve got all the social interest of the brass plus an altruistic streak a mile wide and an interest in history and memory that pairs well with Keyleth’s longevity and her unofficial position as party notetaker.
plus like, “Silver dragons believe that living a moral life involves doing good deeds and ensuring that one’s actions cause no undeserved harm to other sentient beings” that’s just Keyleth in a nutshell
