Diabel emerges as a pivotal leader in the lethal death game, spearheading early efforts to conquer the first floor. Adopting the mantle of a self-styled knight, he forges a coalition of players to devise strategies against the floor’s guardian, Illfang the Kobold Lord. Publicly championing unity and cooperation, he positions himself as a beacon of hope, rallying others toward shared survival. Before the decisive battle, he secures critical intel from an informant, disseminating it across the raid group while orchestrating specialized combat roles for maximum efficiency. As the clash unfolds, he launches a final charge when Illfang weakens—only to perish after miscalculating the boss’s hidden phase, which unveils a devastating secondary weapon. In his last moments, he entrusts the killing blow to a comrade, exposing his prior beta-tester knowledge of the boss’s mechanics. His death ignites tensions among survivors when his concealed beta-tester history surfaces, sparking widespread resentment toward others with hidden game knowledge. Accusations arise that his successor hoarded vital intelligence for personal glory. Behind his altruistic front, Diabel’s covert efforts to obtain a legendary weapon from a fellow beta tester reveal calculating survival instincts. His background remains defined by in-game choices, with no mention of his real-world identity. His arc explores themes of trust, leadership, and the blurred ethics of survival within a merciless virtual prison.
