It never occurred to Saber that "summoning" was used for anything other than creatures such as familiars... as well as herself. Her sword and armour, on the other hand, were a part of her that she called at whim, so long as she had enough prana for them to manifest. But what the young man described did seem rather familiar, though the term for it was different.

"Ah, so it is similar to what the magi of the current era have named 'tracing'. However, they require focus as opposed to potions, and they differ greatly."

Something else had piqued her curiosity further. "Are you a wizard in your world?"

Hopefully not like her advisor, who was prone to nicking womens' undergarments and turning her into a man when he was bored.

"A most noble goal," Saber agreed with a nod. "I have a duty to fulfil, and I must return quickly. However, my attempts to discover a method have met with no success."
