Floating fortress

A floating fortress is a vast, self-propelled, airborne military construct. Housing, or rather built around, a large gandr, a floating fortress can unleash extremely powerful offensive and defensive magic, but may also serve as an efficient troop transport. It is, however, expensive to keep a fortress operational, as it consumes vast amounts of magic fuel.
