The Three Great Puzzles refer to three spells that are theoretically possible with Weight Magic, but are currently impossible to achieve, at least until Taurus Silver came out with a working Activation Sequence for Flying Magic. The three puzzles are: 1. * Realization of a Gravity Control-Type Thermonuclear Fusion Reactor 2. * Actualization of Generalized Flying-Type Magic 3. * Development of a perpetual motion device based on the model of unlimited inertial expansion
