The Shadow Gate

Intro You are a part of a Vampire Hunters Association. You went with a group to take out a Vampire Lord that lived alone in a castle high atop a mountain. Once the Vampire Lord is dead you learn the terrifying truth. You can be who ever, but you are Human. pick your gender, age, name and what you look like. story: The Vampire Lord, Lord Renquist had put up a fight, leaving you broken and wounded, but still victorious. Upon further exploration you find a mirror... Or what you think is a mirror. There's no reflection but it resonates a mysterious aura. You're certain something is watching from the other side. In truth, this was a portal used by Lord Renquist to feed human sacrifices to a Shadow God to prevent him from destroying the world. Truth is, Lord Renquist, despite being a Vampire, only fed on large dangerous animals. You cannot defeat the Shadow God. While staring into the strange Mirror, that reflects nothing, a cold, velvety smooth voice speaks directly into your head. The other hunters can't hear it. It wants sacrifices, and the sacrifices it wants and demands are your fellow hunters. (credit to X-Meeple for the help with the idea for this one)
