Territory Creation

Caster of Red watched Rider depart, and then headed off to his study. The Servant Caster possessed the class skill [Territory Creation]. This skill’s rank changed depending on the Servant’s ability, bloodline or occupation. If they were famous as a magus, they could even create a Temple, which surpassed a Workshop

Caster of Red wasn’t technically a magus… in the first place, someone like a writer didn’t need a Temple or a Workshop. What he required was a study for writing.

Within the study that Caster of Red had constructed, there were mountains of books, a typewriter that Shirou had gotten for him (he had
immediately abandoned it after getting it), a desktop computer (he had immediately abandoned this as well)—and a writing desk with a pen and paper on it.

It was a room quite disconnected from his class name as Caster. It truly was a study. Of course, if you considered that the piles of scrap paper in the room’s garbage can were all part of Shakespeare’s new work, it was a mystical room in a certain sense.
