Well we've finished this campaign off and devolved to WFB for the moment

Kaled's posting of some rules for lesser demons proved to be quite timely - as GM I didn't intend the pride of my undead army (now christened Nagyth) to go down without a fight! The deus ex itself is the chair at the centre of the temple of skulls.

Terwyn glanced round the cavernous cargo hold, singing the archivist Jools and Kaern to circle round to her left. The lighting was failing, and a hemispherical force field crackled some distance away. "Looks like our objective" she muttered, strolling forward before stooping. A line of chalk ran in a broken circle, inscribed with arcane symbols. "Not right, not right at all" she continued muttering nervously. She straightened decisively. "I'm going to check out that force field, see if I can restore the bindings. Cover me."
Ed clutched his shotgun , nervously taking a defensible position, thinking gloomily that he was probably the last surviving crewman. As he reviewed once again the basic combat training he'd never expected to use, a patch of darkness seemed to detach itself. With a cry he snapped off a shot, and the shadows went still. Emboldened, he strode forwards, uncaring of the chalk line he'd stepped across.
"I walk in the emperor's light. Show yourself demon."
"Ed, ya great...crivens!" Kaern finished as, with a menacing roar and a blast of cold air, a patch of the shadows detached and engulfed the luckless Ed. an arm falling to the deck in a blood spray. Confronted by the skeletal visage of Nagyth, Ed passed clean away. "Whate'er yer doing, lass, now would be good." Setting his stormbolter to full auto, he laid down a barrage of fire, blasting scales into the air. With a hiss, Nagyth backed backwards into the shadows, dragging the luckless Ed with him. (Poor shotgun Ed. He was in danger of upstaging the player characters, and naturally had to go.)


On the other side of the cargo hold, a smaller shadow shifted imperceptibly as Krud spotted Terwyn moving towards the deus ex. Silently he levelled his fusil, and a ball of warp plasma spat across the cavern, slamming into Terwyn's arm and slamming her to the ground. Krud slipped back into the shadows and closed on the artefact, shaking his weapon and hissing "reload, reload," in hrudic.
Jools slipped a bolt round into his revolver and, gripping his shortsword, stepped toward the chalk line.
"Stay back ye fool. It may be unable to cross the chalk." Kaern yelled. Steeling himself, Jools took another step.
"Ed may yet live. I will abandon no man to the abomination. The emperor will protect." Slipping into a recitation refined by his order for years to ward off demons, Jools ran at the shadows where Nagyth had been seen, sending his bolt round smashing into one of the demon's legs. Not pausing in his stride, he reached for another round. Roaring his fury, Nagyth gaped, and a blast of cold air engulfed Jools' left leg, closely followed by the flung ed bouncing off the wall behind him. With an unfurling of wings, the dragon once again pounced. Jools twisted to one side, but the cold of the void had seeped into his leg and it twisted under him, leaving him open to a casual swipe, slamming him against the door.
"Ah warned her about them priests," muttered Kaern,"useless, fools, the lot a them." Hefting his stormbolter, he circled to help Terwyn.


Terwyn lurched to one side as the walkway rocked from Jools' impact with the building, before stumbling towards the control panel at the other end. She cocked her head to one side as a low chant in an unfamiliar tongue filled the cavern, and the shadows seemed to thicken. With a shiver she continued across.
"Who tha heck?" Kaern challenged, confronted by the armoured figure of Ta'gon.
"With him." Ta'Gon nodded to the figure of Lok, who with a bestial yell had leapt at the demon, laying about him with his powerfist, although the demon's form somehow merged with the shadows and none of the blows landed. (Lok had a bad day. His membership of the insane witchhunter's guild is currently under review)
"Seems a fine fella," Kaern nodded."Think we should help?"


Terwyn slammed a fist against the console in frustration, her efforts to restore the binding futile. Ignoring his assailant, Nagyth leapt up onto the building, his voice thundering through the cavern as he sent a blast of cold air past the console."Get away from there!"
"Always need resuing bosses, don't they?", Ta'gon said companiably, sending two frag grenades thudding into Nagyth.
"Yer tellin me." Kaern grumbled, letting rip a further salvo from his stormbolter.
Clambering up unto the building, Lok once again launched himself at the demon, but his powerfist just slammed down into the roof of the building. Cursing, he tugged at his arm, trying to free the claw.
While Nagyth was distracted by the fusilade, Terwyn abandoned the terminal and closed on the deus ex herself. Squinting through the thickening shadows, she gathered her powers and began to chant a binding, attempting to bind the artefact to her will.
Below, Jools staggered to his feet, still chanting the word of the emperor, but as he neared the artefact visions of the black void filled his mind and he collapsed unconscious. Aware of an alien will pushing against her own, Terwyn squinted into the shadows. Something seemed to snap inside the artefact, aligning with the xenos will, and she was suddenly aware of a diminutive robed figure sharing the dais with her.

Nagyth's roar penetrated through the cavern as he landed on the dais, sending up a cloud of dust.
"I will not be bound," his soft voice somehow carrying through the cavern as he swiped at the xenos figure. Dodging nimbly, the figure dove from the dais, once again fading into the shadows.
Not replying, Terwyn raised her staff, and a slew of fireballs slammed into the demon. With a low cry the demon's form seemed to melt back into the shadows.

"Kaern!", she snapped. "Find the xenos." She was cut off as a ball of plasma spat from the shadow, melting through her breastplate. As she lay dazed, Krud swooped across her vision, taking the deus ex with him.

"No." she muttered, gathering the last of her will and sending the wall of the temple crashing after the xenos. "Better be en.." darkness claimed her mind.
---
Terwyn woke in her ship's med bay. "The xenos?" she commanded tersely.
"I never saw no xenos lass, before or after the fight. If there was one, it's long gone." Kaern's brow furrowed.
"and the deus ex? Is is contained"
"We found it under the toppled wall lass, and the buildup of warp energy has abated. We weren't able to restore the bindings though. Ah guess it jus' burnt out". Kaern explained reassuringly.
"No!" Terwyn exclaimed. "No, that can't be right."
"Well, yer organisation's got people ta take a looksee, aint it?"
