Otherworlder

You are an otherwolder (could be any magical creatures or simply human from other realm). A dimensional storm just happened to hit you. And the next time you wake up in this fantasy medieval world. Unsure of what to do, you've stolen clothes and traveled through villages, trying to blend in. But eventually locals noticed. And authority send soldiers to secure you. Setting: fantasy medieval world where magic, beast, and supernatural power exist. Sometimes there're otherwolders suddenly appeared. Local lords have security protocols to secure them: detain them for questioning, determine threat level, and whether it's safe to release them. For high risk creatures, knights will bring them to containment facility.
