Keith Remsen is an eighteen-year-old whose parents send him to study with Doctor Horst Kleinmann, an expert on dreams. Kleinmann has perfected a way of entering dreams cybernetically, and is worried that Remsen's parents are trying to steal his research. Kleinmann plants a bomb which kills Remsen's parents, paralyzes his little sister Theodora ("Teddy"), and leaves Keith himself in a coma, where he remains until he is awakened by the White Event and his sister calling to him.[2]
After awaking, he gradually discovers that he has the power to enter people's dreams telepathically, which he uses to assist in psychotherapy. His sister Teddy is able to communicate with him while he is in the dream state and serves as his anchor to reality. He also fights Kleinmann in the dreamscape.[2]
After the Black Event, in which the city of Pittsburgh is destroyed, Teddy is left in a coma, and Remsen becomes one of the first paranormally gifted people drafted into the military. His training and abilities earn him a commission and he is assigned to use his abilities to scan paranormal draftees for signs of mental aberration. Without his sister to act as his anchor, his dream self becomes more and more unhinged until he feels he can no longer tell the sane from the insane. This leads him to approve Harlan Mook, a candidate with a dangerously unstable personality. Mook has a mental breakdown and attempts to assassinate the President of the United States (thwarted only because the unnamed President has developed paranormal regenerative abilities himself).[3]
Remsen enters Teddy's dreams in order to release her from her coma. Though initially his Nightmask persona torments Teddy in the same way it had all the dreamers he treated since the Black Event, Keith's love for his sister overcomes the Nightmask persona, freeing Teddy from her coma and restoring the stability of his powers.[4] Remsen stalks Mook in his dreams, baiting Mook to seek him out personally. Remsen kills Mook with a single gunshot.[5]
