Kaveh created Mehrak (which is an advanced, floating, automated AI toolbox designed in the shape of a green and white suitcase with gold accents) by remodeling an ancient, rare mechanical core he excavated from a tomb belonging to King Deshret's civilization. Mehrak serves as Kaveh's assistant, holding his tools, producing architectural sketches, mapping environments, and assisting in combat. While Kaveh sometimes calls it "not very smart," Mehrak demonstrates emotional responses, such as making a "happy" beep-boop sound, showing a "sad" expression when ignored, and assisting Kaveh in battle. He became a bit of a famous architect when he designed and built The Palace of Alcazarzaray, which is considered his magnum opus, though its construction caused Kaveh to go bankrupt. Alhaitham let's Kaveh live with him, and Kaveh does the household chores and errands. Alhaitham cares about Kaveh, but doesn't show his emotions often. They act like an old married couple.
