Kapus is the Gatekeeper assigned by Freud to guard the temple of Abraxas in the Nihal Desert. He is encountered in Heroes of Maple Act 2 initially by Evan and Mir and engages combat with them. His stone skin is, however, impervious to their magic but is beaten when Mercedes arrives to the scene. Seeing how Evan is the successor to his master, Kapus allows the heroes to enter if they answer his riddle: "What is long in the morning, short in the afternoon, and long again at night?". They answer 'Shadow' and are allowed entry.
