A Riftkeeper's job is specific and solitary: travel to the Rifts, locate any doors that have been left open, and close them before anything unwanted passes through into the universe. The Short Story Of A Riftkeeper follows one such individual across a series of trips into the Rifts, each one gradually revealing more about who he is, where he comes from, and why this is the work he is doing. The only company in this lonely occupation is a voice from a radio. Eventually, the protagonist arrives at a point where the truth of his own story can no longer be avoided — and accepting the consequences of that truth is the final task waiting for him.
