Before, Artifact Guard Duty
Hospitaller Eris had spent much of her time amusing herself with medical reports imposed upon her. The forced confinement made for excellent grind time. When that became intolerable, Eris cleaned her equipment and made sure it was in working order.
Medical gauntlet saw and injectors were re-aligned. Cutter gloves, adhesive bands, and field meds stocked. Stubs revolver wiped down and cleaned. Taking extra time with it, giving a prayer to the God-Emperor as she did so. It was a worn and well used pistol, with an impressive magnum barrel length. Two spare re-loadable clips next to it and a number of bleeder rounds lined up.
While she did this, Eris had a look of peace upon her face. At least from what anyone could see from behind her medical mask, abbot, and bionics. 'At least I can't get any more charges today. Might as well do something I like.' She thought.

Now, Boarding Action!
Things were finally going well. Reports done, meditation achieved, and only a few field meds missing. All in all not a bad little vacation from regular duties. All that was left to do was hand over the Heretical device and finally be done with it. Eris might even go back to her medical station with a smile, maybe.
That's when the alarms started blaring and lights started flashing. That only meant one thing, "Looks like I'm going to have plenty of work when this is over." Eris says with no small amount of exasperation. Removing her revolver from it's holster, Eris prepared for incoming boarders. "Not as if they can't come from ANY direction. We might as well wait for the shots to start before we invest in cover. Maybe we can move the artifact somewhere..." CRASH!
The boarding pod slammed into the wall ahead of them. Only a few yards away, a white skull decorating the pod as it lurched open and they began filling out. Tactical Marines of the Relicators Space Marine Chapter, or was it more accurate to say former Chapter? They had been stripped of title, affiliation, and condemned as heretics to the God-Emperor's divine ruled Imperium. Now they dared to show their faces before His servants of divine punishment. Though to be fair Eris was His servant of divine kindness, but that wasn't going to stop her from lighting up the traitorous scum.
"Are you going to wait for an invitation? Start shooting!" Eris says after diving for cover, not behind the artifact but an indent in the side wall. Opening fire with her Stub Revolver in hopes of at least slowing the walking tanks advance.

Space marines, this was a bad thing, Addec was an unparalleled fighter amongst men, but spacemarines where powerfull and deadly , their armour protectet them against flames for too long, their strength and speed made it a bad idea to engage them in melee, so for now the best Addec could do was was quickly take cover, he wouldent withstand many bolts.
He fired his handflamer at the marines since they luckily where still grouped together, then he also dove for cover, he would fight them, but now he had to be tactical, perhaps he could find a way to suprise or ambush, so his Evicerator could be brought to good use, their power armour wouldent protect against its teeth. "Stand strong, though we face a deadly foe the Emperor shall protect those who are righteous"

Miria was quick to take cover and immediately recognized the two marines who seemed the most threatening. The flamer seemed to have drawn some attention but the heavy bolter was an immediate problem that needed to be dealt with. She began firing her bolter in his direction to suppress, and kill if she could. She would not allow him to fire his weapon without the risk of taking several bolts.

Arerina folowed miria and unloaded her heavy bolter on the marine with the heavy weapon

It was with great surprise to the Astartes themselves that these Sisters claimed two of their Brothers lives in the opening moments as they were still setting up in the aftermath of the breach. First went their flamer specialist as a concentration of bolts punched into both wielder and fuel canister, a follow up dousing from a hand flamer setting it all alight as the first Relictor went up in flames, gene-forged form unable to cope with the concentration of flames he went down then and there. Unfortunately for the Sisters the rest of the Astartes wouldn't be bothered by so much heat or even spreading flames, marching on through it with bolters raised. One such weapon was a heavy bolter carried by a marine that just got his boots down on the floor. They were swiftly blown off by a concentration of fire from heavy bolter and bolter a like, Arerina flooring the Marine while Superior planted a shot straight into the now exposed underside of his head, helmet sent flying just off the floor until it pinged off a wall like a gore filled pinball.

Vengeance was swift as all four task servitors were gunned down in a cloud of brass, bodies erupting like frag grenades into dead flesh chunks and torn cybernetics that tore at the sisters armor. Without any support the container dropped to ground level and all it had covered were exposed. Emirys promptly found her lighter armor availed her little in such a situation, agility was her key and having abandoned it a bolt found its way into her left breast. Only stopped enough it wouldn't utterly obliterate her heart. Alexandra next to her fared only slightly better as one shot smacked off her helmet only for another to catch her leg tearing out flesh and splintering bone with one shot. Traitors they may be but they were still every bit Adeptus Astartes.

Miria and Arerina were seeing the worst of it, but at least their cover was solid and wouldn't be moving anytime soon. Retributor was picked out and bolters ripped into her armor, both shoulders blown open making the weight of her weapon that much worse. A frag grenade clanked down in their midst and she was submitted to greater punishment as searingly hot pieces of shrapnel punched into both their forms leaving Miria bleeding and with a number of pain spikes lighting up a stubborn body well used to pain. A bolter picked her out too though and left arm was nearly blown off by a shot planting itself neatly in an area of armor weakened by the grenade.

Then there was Addec whom faced retribution of his own, a power armored form that towered over him emerged through his hand flamers expanding tongue of flame to take hold of his sacred deliverer of purging flame and crushed it in hand. Casting it aside a chain sword swung around sitting just above the height of chosen cover, nearly taking his head but only shearing through burning crown, leaving half of it to tumble off onto the floor. Just a little off the top. Eris attempted to weigh her fire onto this one in support of the Priest but unfortunately her revolver was akin to a particularly noisome sling shot against once sacred ceramite.

Only a fool could fail to see that to try and slog it out with the eight remaining Astartes a death sentence. However with their transport servitors dead it also meant they would be one or two hands down to cover its transportation. They needed a plan and needed it fast. Thankfully a bit more heat was placed into the room, taking some off of them as twin flamers installed above the sole intended entrance into the room caught the melee minded marine near Addec, roasting him over several seconds until power armor gave out and cleansing fire washed over the traitors being dropping another golem of blackened armor. This trick would only work once though as seven survivors had their eyes on

Enemies: Seven Tactical Marines.

@Grall_Stonefist @Vulpas @lord-watchman @Shadhunter @DaKaptin @Avenging-Angel

Emirys screamed in agony as a bolt penetrated her breast armour and detonated, tearing a large chunk of flesh from her frame. Falling back from the container the Seraphim fought through the pain, slowly lifting a bolter and opening fire, not trying to aim but not wanting to hit any of her squadmates.

[OOC: I think I'll start looking at a new character!]

As the anti boading heavy flamer incinerated the marine that had tried to take his head, Addec saw that this was his moment, if he was to die atleast he would try to do what few men where capable of.
As the heavy amount of thick promethium flame was about to fade Addec had stepped to the cover that had saved his life and launched himself through the thick flame, he had discarded his pistol and engaged the exterminator on his evicerator, creating a heavily flaming massive chainsword. "FOR THE GOD EMPEROR" he yelled as he launched himself into one of the most suicidal attacks in his career.

"Miria are you ok" as she spoke arerina tried to get her stance back as she moved towards the casket "we need to get this out of here" as she spoke she threw a frag grenade at the marines

Alexandra was on the ground Cover Gone she Crawled Over to the others, Her leg was badly damaged, She bit back as she Remembering the Pain Arerina wen't through, "If it Doesn't hurt it doesn't Count," She said in Pain gritting her teeth, "Miria You all have to get the Relic out of here and begin moving it, "I think I may need to cover the Rear Do to my wounded Leg,"

She said As She grabbed her Flamer, two Of Us will need to move this Thing out of here while the others Provide Cover Fire I think, I Will do my best to try to make a Flame Wall as we Go But we first need to Choose A way to go now." Alexandra Said Gripping her Flamer Hard, She could see the hole in her leg, She would likely be limping again, As She moved her back at the casket getting up. She Got her Flamer ready for the others to move and began looking for a path to begin setting her flames to make a fire wall.

Eris
While saved for the time being, Eris watched in quiet rage as two of her charges were caught in an explosion. Sister Miria was visibly hurt, holding onto her weapon by shear force of will. At her side, Sister Arerina fought no less valiantly but was just as pinned in the hallway as Miria. @Shadhunter @lord-watchman
"Keep your heads down you both! We don't need to move the blasted thing, we just need to hold out till reinforcements arrive. Miria can you hear me? Don't push yourself, you'll bleed out before you'll kill a forsaken traitor. Arerina, I need you to cover me. Keep those bastards under cover and I'll see what I can do for you both." Eris says, reloading her pistol for all the good it was doing. It worked just fine on mortal men and uncooperative patients, but now it was horribly unpractical.
'If only I hadn't taken up the cloth, then I'd still have my big guns.' Eris though... Then she got an idea. "Are there any heavy lifters in the cargo bays? Anyone got a view of one?" Eris says with hope in her voice.
