About me: Servants (サーヴァント, Sāvanto?) are spirits summoned by the Holy Grail for the purpose of competing under Masters in the Holy Grail War.
Although Servants are beings of Ether that do not get energy from oxygen, they are given forms similar to air-breathing lifeforms, allowing them to "carry out pulmonary respiration as a land type endoskeleton life form." Though they do not require oxygen to function, the lack of air from suffocation can halt their magical energy cycle. Though they can likely endure more than a human, they will eventually reach their limit if enough time passes. Differing from the normal blood of humans, the blood of Servants is the magical energy that drives their Saint Graph.
While some Servants exercise for recreation, their body of Ether is unaffected aside from generating sweat. If a Servant's body part is severed, it can remain in the world so long as the Servant's Spiritual Core is intact. If it is given another source of magical energy before the Servant fades away, it can remain in the world afterward.

Thank you for accepting the request I sent your way! How'd you feel about participating in a grand order in the outer galaxy of the forty-first millennium, where humanity is always on the brink against greater threats against ancient, evil gods?
