The Swordbearer. As they bound back and forth inside rooms with three walls and three floors... This is the crystal room, the first floor where you drop on in from the hallway, second the crystal room level, and lastly above where the gatekeeper resides. I am there also, among their ranks. The swordbearer in the grimoire is a major in the Hive's army. There are three places from which they view my target, but only one whence I strike. The three places would be the three windows, or the two doorways and the windows as a collective singular window, and the place where he strikes would be where his sword is. I deal my dealings as one glides across a "U" shaped conductor. This references Crota, the "U" shaped conductor the pattern of Crota's rotations, and the gliding could reference the way he moves. I am a high pitch and a low pitch. This references the strike types with the sword it carries. Pinch me, and I will respond with the tearing of reality. The tearing of reality is it cleaning you with its sword, and the pinch could reference stealing, or simply bothering it.
