Descent into Darkness was a biography of Dan Sylveste, written by Pascale Dubois during his captivity following Girardieau's coup. The digital book was capable of simulating real life experiences of Sylveste, with the "reader" choosing to be either an observer or participant. The original intent of the work was to discredit Sylveste and destroy his character before the entire colony of Resurgam. Unfortunately, even Sluka, an enemy of Dan, admitted that the work had mixed results.
Originally unknown to all but Pascale, during her interviews with Dan she had copied his beta-level simulation of Cal into each copy of the biography. This was done at its request, as it considered the times to be dangerous and disliked having its existence at risk.
