"Most people unquestioningly pursue what society tells them to pursue. A mindless herd. But then there are those that think for themselves. Only these stubbornly logical minds could join the Elevated Caste. I questioned everything I thought I knew, and felt prepared."
In the same room is a cassette player and a cassette. When Philip Buchanon inserts the cassette into the cassette player, Eloff begins to speak. Eloff's death can be witnessed on tape, while he is being murdered by a Tuurngait Infected.
Eloff is one of the four residents of the mysterious world in Requiem, along with Phillip, Tom "Red" Redwood, and Dr. Richard Eminiss. Eloff's voice can be heard throughout the world. As with his role in Penumbra: Black Plague, he created audio journals to communicate his thoughts. However, Phillip was able to listen to them without the need for a cassette.
It was mentioned that Eloff attempted to commit suicide by swallowing a cyanide pill as he was captured by one of the Tuurngait Infected during the last game. However, it was revealed to be a dud.
Like Phillip, Eloff seems to have no idea what the world is but tries to understand it through his recordings. Eventually, Eloff realizes that someone (Phillip) is listening to his thoughts and slowly descends into madness. He also reveals that he made contact with Tom "Red" Redwood, who he claimed to be "talking gibberish, threatening me."
Eloff was last heard during The Engine level, frantically warning Phillip to not make the same mistake as him. It's possible that Eloff was to spend an eternity alone in the world, trapped forever.
