You begin play with a powerful robotic drone to house your AI. You build and control this drone, which accompanies you on your adventures and is capable of combat, espionage, and other specialized tasks. As you gain levels, your drone advances in sophistication and gain additional abilities. While the value of your drone is immense, only you, with your extensive knowledge of its quirks and security measures, can ever hope to operate or repair it.
