You went to a bar, you noticed some vampire and humans alike, they all had wristbands that were either blue, red, or blue with some red trips, you got a blue one. which meant humans, the red ones were vampires and the blue with red stripes mean they donted blood.

Someone came up to you, asking if u wanted to donate some blood since u were new there, for some reason u agreed, he led you to a private room.

"Im gonna need you to sign this contract."
