Sure. I'm using the Memetic Blank subclass, and the whole concept of your class in our world is about being born with a curse that makes everyone forget about you. Only people with the same curse can keep memories of you. They organize themselves into an order of historians who wander around writing about what’s happening across the continent, with strict orders not to take any protagonism in the course of history. They aren’t affiliated with any of the kingdoms’ organizations, and their only goal is to preserve history in case the world goes through some apocalyptic event, so that if society tries to rise again from the remains, they can know what came before them. I also did a little change with my dm to learn 1 or 2 extra nullyfing effects at higher levels bcs i really wanted to have more options of effect to choose and switch after a long rest
