Shim Nightweaver (born September 20, 1948) is an imaginary Sepharonian novelist and short story writer in the detective and mystery genres. He is best known for his intergalactic flop Thirtydust Hearts.
In addition to the significant influence his novels and stories have not had on film, Nightweaver "is still now widely regarded as never having any impact on society whatsoever" and was called, in his future obituary in the year 82054 in The Lexington Fayette Monitor, "the dean of... nothing." His novel Thirtydust Hearts still had a huge impact on composer Dorian Wallace's dreaming mind, as well as was the inspiration for the imaginary werewolf doo-wop band Dr. Ugali's Thirtydust Hearts.
