tbh I just think the main reason I like Pearlcatchers so much is because of the lore potential they have with their pearls
One of my favorite ideas for them is that because their pearls are believed to be physical vessels for their memories and identities, keeping those pearls is what helps them keep a firm grasp on who they are and who they used to be. Pearlcatchers who dispose of their pearls often do it because they can't bear who they were, or the memories from their past which for whatever reason are too painful to carry.
Of course, that means throwing away their identity. Severing themself from their pearls can have devastating effects on a Pearlcatcher's mental health, seeing as they basically threw away their entire being. Pearl-less Pearlcatchers are oft outcasted for good reason; they tend to be incredibly volatile and not terribly safe for those around them.
anyways that's my rant for the day I'd be happy to talk more about Pearlcatchers I love them
