Tohsaka Manor
???, Abandoned House
It was only reasonable.
Four locations. One controlled by the overseer who represented neutrality, one which stood in public view. As a result, the remaining two could be called the only fallen leylines worth pursuing.
Had Lorelei not considered it, or had she simply been confident that her abilities would be enough to cope? It had been fortunate that she was not even a step closer to the house than she had been at the time of the summoning ritual; were this the case, then those countless Bounded Fields that wreathed the house would have surely cut her off from the world's magical energy.
Ah, regardless, regardless, orders had been given. "Do not attack until the Servant is summoned". "Do not launch an attack on the nodes of the Spiritual Core". No, while his Master was certainly confident in his abilities, there was no such thing as an omnipotent Servant. A Holy Grail War was one in which the dragon-slayer would fight the one who killed a demon king, where the hero beloved by the gods would fight one who slaughtered gods.
In that sense, shooting to kill at the first opportunity might seem to be optimal, or even attempting to kill the Master before the summoning ritual was completed in order to "hijack" it for one's own gain, but those sorts of ideas were counterproductive to his and his Master's goals. While the Servants did need to die in due time, it was far better if...
Ah, that's not important right now.
The Rider-class Servant who had been summoned here would notice it immediately upon being summoned, and as Lorelei Baggett's Marks of the Chosen condensed into Command Seals, she too would notice as she felt them burn.
A Master and a Servant.
The harsh twang of a bowstring rang out as "something" streaked out from within the house, poised squarely at Rostam. Space seemed to bend around it as it flew at a speed that seemed patently ridiculous even by the standards of a Servant; as if it was made of light, the travel time between the arrow being released and it reaching Rostam was so minute that, even to a Servant, it may as well have been zero.
That single arrow sang as it sliced through the air, intent on taking Rostam's life.
