Here is a re-cap of one of our first adventures of Deathwatch. This is the second session from the GM Kit adventure "Shadow of Madness"

Receiving key topographical data from Lt. Drayle, the Kill-team boarded the supplied Land Speeder Storm and set off in search of the mysterious glade, the local fabled refuge from the ghosts of Baraban and source of the disconcerting intel that brought the Kill team planet-side from the beginning. After a few short hours, they broke free of the encapsulating underbrush and canopy as Tactical Marine Haakon piloted the Storm into the tranquil setting of the glade. Though the sight of numerous battles, the evidence of which still stained the surrounding vegetation and ground, the glade held an eerie emptiness, all save for the monstrous shadow that sat, unwavering, in the center of the clearing. The source unknown to any, like the air itself battled with the rays of the local sun.
The team set forth immediately combing the area for intel and clues. Acheron tuned his Auspex and noted key patterns of wavelength displacement in the area that should contain the shadows source. He caught upon the idea to use the archeotech illuminator and uncovered both secrets at once. Lucien was intent upon the perimeter as he noted movement to the west and leapt into action, igniting jets of plasma flame to carry him aloft into the soft underbrush surrounding the glade, his prey had escaped for the time being, but he knew he would find them. Haakon awaited the Tech-marines analysis with the Speeder, wondering why he had never read any intel regarding the native wolves of Baraban as he heard their cries on the wind. Were there wolves on Baraban? Acheron, with the help of team leader Octavius, scoured the face of the xenos device as it was revealed by the ancient illuminators, coming startlingly upon his own, helmetless, reflection upon the face of the device, staring back into his own eyes with a dismal, haggard, gaze.
Ezekial, his mind focussed and set upon the xenos artefact brushed away any attempts it may make upon him. He saw through the images dangled before the others eyes and touched the centre of the xenos device. He felt cold, malice, alien emanations. Like the device was asleep and merely dreamt of the terrifying duties it would unleash when awoken. He informed his kill team and quieted his mind once more, falling back through his life to a time when he stood before the dark cloaked Librarians of his chapter, reciting the complex mnemonics that would preserve the forbidden secrets within him, allowing him to recall, and protect those secrets when necessary. His mind caught upon what he searched, and with a rush of sound like a grand battlecruiser emerging from the warp, his mind returned to the present, opened his heavy lidded eyes and whispered.
“I know what this is”
As the fates were cruel to all clinging to hope on Baraban, that was the moment the Tau strike team open fire. Filling the glade with hundreds of fragments of focussed plasma as they attempted to box the kill team in, and eliminate their interference. The battle was quick and gruesome. The battle brothers, called by Octavius, held formation and moved systematically towards the first pair of Tau whom presented themselves. Bolter rounds softened the enemy as Octavius snapped of a missile into the doomed pair, wreathing them in fragment shrapnel. Their cloaking suits malfunctioning, the Tau pair fell quickly to combined melee and range focus.
The battle turned to the east when the second Tau pair struck, and was answered by the searing blast of warp fuelled destruction unleashed upon them by Ezekiel. Their reply was gruesome. Half a dozen rounds punctured Ezekiels power armour, calling forth his blood and rendering him injuries that would have felled dozens of lesser men.
Haakon, pumped round after round into the fray, pulping one previously unknown enemy to the north as he walked bolts through the area like a brush stroke. The geyser of blood and halo of ignited promethium was a reward that held a disturbing sweetness that nourishes all Astartes. The final enemy faded away, his whereabouts indeterminate. Another ghost vanished from within the hellish soul of Baraban.
Lucien continued to remain en-guard for the rogue assailant, while Octavius summoned aid and munitions from Drayle at outpost 420. It was for nought as Ezekiel was able to recover himself from the wounds he undertook upon the battlefield as the surgeon stood by monitoring him, amazed once again by the marvel which were the Adeptus Astartes. Acheron oversaw the engineers ring the “Delirium Trellis” with potent charges. As the ignition caused the structure to shatter and collapse, tainting the surrounding area with a dark and bitter ash, Octavius, dwelt upon his last conversation with Lt. Drayle.
“What you are telling me is amazing, yet not unbelievable. I have felt that there must have been a reason for the glade to be a refuge. However, it is not the only refuge from the ghosts that I have heard of...... Lord Astartes, do you believe there might be more of these devices here on Baraban? Would the Tau know of them as well?”
