[Saber's only a bit more into the sector before she catches sight of what seem to be the tail ends of a few raptors. Even with the light of Excalibur, though, she can only see so far-- so the reason they haven't turned on her yet, the one they are chasing and the fact that they are doing so actually, is unknown to her.
Regardless, she wastes no time covering the distance with a leap and charging the pack while they're yet unaware of her presence-- slashing one down through the back, and taking out two on the side, before the others grasp that they're getting flanked from behind. They turn and respond as a unit almost immediately, jumping at the small knight to tear her apart; only to be cut down to the last of them in quick succession, the trails of light left lingering in Excalibur's wake like that of a shooting star's tail.
Compared to those Nurses, these weren't even enemies]
