You unlock this thread with the key of imagination. Within it is another dimension - a dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into the Twilight Zone Thread.
In this game first one person writes a Rod Serling style intro for a Twilight Zone episode of our invention, then the next person writes the twist that happened in that episode. Oh, and please don't use real episodes, kinda ruins the fun.

Presented for your consideration, this is Tod Stevens, a man on the edge of everything, and he is about to be pushed, by the hands of fate, into....the Twilight Zone.
