Griffin Sky

Griffin Sky is an unmanned Mobile Fortress that belongs to England, it was used by Carissa to act as a defensive line when the opposing forces from Necessarius arrived at the Buckingham palace. Carissa deployed for about 20 of them at the same time.

Characteristics and Functions
The can be described as objects that have a similar form to a hang glider, however, they are huge with almost 80 meters across making the giant object around the same size as the large passenger plane Sky Bus 365. They posses silver metal parts reinforcing them at important points that look like armor.

They are meant to be used to attack strongholds on the surface, so they cannot fly as high as an airplane and they are not as flexible or practical as the Witches's Coven Compass because they are unmanned spiritual items, but they are the country’s best at linked attacks. Their main form of attack is turning their own shadows into huge 20 mt stake to attack.

While in automatic mode the Griffin Sky will try to use the lowest amount of strength necessary to destroy a target, however this can be manually changed so that the mobile fortress will always attack with the strength level signaled by the one who controls them.

It would appear that the lance that is created from the Griffin's shadow is solid, and since the shadow and the mobile fortress are connected, this has the demerit of if one can get a hold of the lance and twist it, that can affect the Griffin's trajectory or there is also the fact that halting the lance in place would immobilize the main body of the mobile fortress, this was the main method that the Amakusa and Necessarius used when fighting with the Griffin Sky
