Floor Master

Floor Master (フロアマスター) is a title given to certain Masters in the Moon Holy Grail War after Chakravartin manifests in Fate/Extra Last Encore.

Characteristics
After each of the seven floors became independent, the last Master remaining or strongest in the history of the floor is chosen to manage it. They can utilize its resources to change it should they wish. They must be defeated for another Master to ascend to the next floor, although other Masters can descend to lower floors without issue. Should the Floor Master wish to ascend, they must also kill another Master, but the exception is Dan Blackmore who was revived after his death in the proper Holy Grail War. After their defeat, the floor is also destroyed.
