Schnick. Kothar's short blade slit the maintenance worker's neck, a spray of blood painting the wall of the tunnel. It splattered across the open pipe as well as the glowing yellow tube, giving the light within the tunnel an orange hue.
The slain worker gave a few choking sounds, but then fell limp in Kothar's grip.
Kothar slowly pulled the worker's arm out of the pipe, so he could make enough room to continue up the maintenance tunnel.
The worker's arm slipped out of the pipe, her fist clenched tightly around a glistening, red, gelatinous mass.
It was about the size of a small melon, large enough that it would obstruct the pipe, making the worker's purpose in removing it clear.
Kothar stared at it in fascination, poking at it with his blade, it was almost jelly like, but still tough enough that it wouldn't break apart easily.
