The Merkabah is a personal assault cruiser assigned to each Gralsritter Dominion Knight in the Trails universe. It is a modern airship using the safekept artifacts by the Septian Church as the power source, with cooperation from the Epstein Foundation's orbal engineering department.
- Optical Camouflage: The cruiser's exterior armor is laminated with retro-reflective material to blend in any environment.
- Stealth: Keeps the ship undetected by enemy radar.
- Barrier System: A forcefield to deflect enemy attacks.
- Beam Cannons: The cruiser's tack/defense weapons.
- Stigma Cannon, Mechidels (聖痕砲メギデルス):  The most powerful weapon of Merkabah. Under the activation of Mode-S (Stigmata), the Dominion captain channels his/her stigmata to the ship's power source, amplifying its maximum parameters, with the weapon charged for use.
- Its possible that the Stigma Cannon was installed after the events of The Legend of Heroes: Trails in the Sky the 3rd, modeled after Anima=Mundi's strongest attack.
