Unfortunately Katia's confidence, proper and pious as it was, was short lived. Her humming powersword bisected a loading servitor with two vast magnetic claps for hands, dropping it to the ground in two parts which gouted biofluid in pressurized jets. Her leather parade boots slipped in the ruin of cables and she lurched sideways. The mistep saved her life as powerful tentacles of hammer wrought iron punched through the ferocrete wall in a spray of dust, whipping through the air she had occupied a moment earlier. A large figure clambered through the breech in the wall, nine of the hydro mechanical tentacles giving it an appearance of something like a spider and something like a squid but entirely neither. The creature at the center of the writhing limbs might have once been a tech priest, but he, or more accurately it had long since given in to the ruinous powers. The metal grill that would ordinarily have graced a priest of Mars had been replaced with a piece of carved blue crystal that duplicated the effect. The remainder of the face was in shadow but Katia felt that was rather a blessing. The eyes beneath the hood blazed with blue white light that didnt seem to illuminate so much as throw sharp unnatural shadows. The red robe was woven with patches of shimmering blue fabric and golden inlay that hurt the eyes to look upon. Katia noticed that even when his skeletal body was not supported by the tentacle things it seemed to hover an inch or two above the ground. An ozone stink bit at the back of her throat and the reeking stench of the warp permeating the air.

"Remove impediments from the formula, only by nines," it buzzed metallically.

"Warp spawn!" Katia shouted swinging her bolt pistol up into line and firing of the entire magazine in a flurry of bolt rounds. The Warp-priest swatted the rounds from the air with a single swipe of a mechadendirte, the metalized tentacles sparkling under the impact of the bursting shell casings. Another of the tendril reached for her and she batted it away with the blade in a shower of sparks. She backed towards Zeb, keeping the tentacles from her with a series of sharp savage parries. 

"We need to get out of here!" she shouted to Zeb, ducking as one of the tentacles swept over head, dishing in a plate of 2 inch metal like it was tin foil.
