Aerostone Vault

Made with the same arcane technology that powers the aerospires, these stone vaults are secure and easy to transport when harnessed to conventional beasts. The vault glides on a pillow of warding essence that can sustain heavy loads and provide self-stabilizing traction. The lack of wheels, gears, and mechanical parts greatly reduces the cost of maintenance, but if anything were to happen to their warding engines they’d be nothing more than hollowed-out rocks, blocking the road.
