One Dark Night begins with police and emergency responders in the apartment of an occultist named Karl Raymarseivich Raymar, who was recently reported as deceased. Police discover that Raymar had an apartment full of young, dead women in various states of decay. Adding to the eerie scene are the bolts of electricity that seem to shoot from Raymar’s fingers as he’s lifted onto a stretcher, punching a hole in the ceiling.
As it turns out, the elderly Raymar was telekinetic. He took his ability to move objects psychically to a new level when he began kidnapping young women as a source of fuel. One Dark Night introduces audiences to Raymar’s form of psychic vampirism, where he feeds off an innocent person’s energy.
