It's night time as you awaken in a room. The sun was just beginning to set. At your bedside table, you find a note.

Welcome to Mystery Mansion, a place where a select few can enjoy. You have been selected to participate in a party. Please be mindful that all species are invited. Don't be afraid thought, there are hunters hidden among the guests to protect you. The masquerade party is tonight, be prepared.

Along with the note, there was a map of the place. You look out the window to see a forested area.. You could go explore the place... Or start to get ready for the party?
