You ever hear of the Stranger Ritual? No? Well, perhaps that's good, perhaps you're safer not knowing and perhaps I shouldn't tell you, seeing as how this ritual can be a little dangerous.  Still want to know? Very well. I'll tell you.
The Stranger Ritual is a ritual that allows you to contact something from outside this world, something beyond the limits of human understanding. Some say that the ritual allows you to contact Death itself.
In order to perform the ritual you'll need a few things. First, you'll need a door, preferably a wooden door. It cannot have any windows or peepholes and it must have a lock. Next, you'll need two candles, one white and one black. Then you'll need a gift. It's important that the gift not be something you have a personal connection to. It is advised to offer something you have bought on the day. Candy seems to be a wise choice. Then, you'll need a piece of chalk or some other writing instrument - chalk is probably the best choice.
