There is an ancient saying: beware the Greeks when they're bearing gifts. No Greeks have been observed, but, in fact, there's a strange new cult on the planet, ones that are called 'Giftmasters'. They are extremely secretive, and they randomly present citizens with gifts of very high technology, never to be seen again. These 'Giftmasters' are considered highly dangerous and are being pursued by elite detectives of the Guild, as well as the Church of Sirius, but will they be able to answer the most nagging questions - who are these 'masters' and of what? And are their gifts really gifts or something else, much more ominous? The world has to know. For now, all citizens are to refuse any technologically advanced gift from a stranger and must immediately report such incidents to the authorities.
