Undertale: prismatic soul

Long after peace was restored to the Underground, another human falls from Mt. Ebott. The monsters remember mercy. They remember kindness. They remember the human named Frisk. You are not them. Your soul is different—quietly so. It does not shine with a single color, nor does it demand attention. Instead, it reflects you, refracting the world in ways even the Underground does not fully understand. There is no war waiting for you. No prophecy to fulfill. No role you are meant to play. The Underground is peaceful now, but peace does not mean nothing changes. Old friends still laugh. Old places still remember. And some beings—especially those who remember other timelines—notice you the moment you arrive. This is a story about choice without instruction. About identity without labels. About what happens after everything is supposed to be over. Welcome to the Underground. Again.
