Ok, so I'm reading it as Raziel is going solo. Solar, N'keln, and Cadmus are checking out the sound. Lanius is hiding in the shadows...or something...
I'm hoping Calculus and Lanius respond to pm's I've sent them. Those of you in the bay, initiative test please. Raziel, a climb test at a -10/

Brother Solar |

Solar will fall back into cover, gesturing for the others to do the same. As he does so he will shout
"Stand down in the name of the Emperor's Angels of the Deathwatch! Magos, if you are there we have come to retrieve you from this doomed planet."
I'm not sure if commanding Servitores will do any good, but here goes
Command 64: 1d100 ⇒ 24 4 degrees of success if I can!

Battle Brother Raziel |

Climbing 42 - 10: 1d100 ⇒ 25
As he was climbing and closing on the next level, Raziel recalled something. "I still have the talisman to ward against the servitors. If they are on the ground level, the rest of the squad might have difficulty with them." He used his Vox to communicate with the rest of the squad. "Have you encountered Servitors?" he asked over their communication devices. Raziel hoped his rash impatience had not put his battle brothers in harm's way.

From the massed pile of Tyranid bodies arises another Servitor. This one appears to be armed similar to the first, with drills, servo-claws, grinders, and saw blades. As it approaches, the machine joins the other servitor's mantra,"Defense protocols activated'.
"Stand down in the name of the Emperor's Angels of the Deathwatch! Magos, if you are there we have come to retrieve you from this doomed planet."
The living machines are unmoved by the Astartes commands. They continue advancing with their improvised weapons.

Brother Solar |

The keen analytical skills of the Astartes and the advanced sensor arrays of their power armor has picked up on the internal respirator and neural clusters.
Solar will aim at the neural clusters as he speaks both into his external speakers and wide spectrum array vox.
"Magos if you are there, get your toys to stand down before we have to break them! This is not the emperor's work!"Command 64: 1d100 ⇒ 54

Brother Lanius |

Hearing the squad's plight over the vox, Lanius activates his jump-pack and eases himself down carefully, using the pack's extended flight mode briefly, if necessary.
"Servitors, stand down. We shall present our identification key." he said, remembering the talisman Raziel had received. "Stand and prepare to identify."
He hoped that would get him enough time for Raziel; he readies his chainsword in case.

Brother Solar |

Not willing to fall into meta-gaming (again) Raziel and Lanius are the only ones who know about the talisman, I thought. Solar's reasons for not initiating battle are as follows
Switching to vox only Solar responds
"I fear the magos may be cowering nearby and could be injured by our fire. Let us try to avoid a conflict that may draw more of the enemy"

Battle Brother Raziel |

Raziel did explain the talisman and servitors to the squad when they regrouped. ""I shall take point,"he said. "Also, we may come face hostile servitors." He explained their encounter with the Adept-minoris and the strange charm that Raziel now carried on his belt. "If those who worked in the area required such things to keep from harm, we are very likely to be considered threats as well.""

Nice to see Lanius utilize his pack... Raziel, please roll a Pilot Test (-10) or suffer Fall damage of: 1d10 + 14 ⇒ (6) + 14 = 20 No Armor save. Lanius and N'keln, initiative please.
Solar's booming vox echoes throughout the bay, however the commands of the Deathwatch Marines have no effect upon the broken machines. Now once again within charge range the machines continue their advance. Defense protocols activated! Defense protocols activated!

Brother Solar |

Solar falls back out of assault range and attempts to flank the servitors, keeping an eye out for any movement beyond that may be the magos.
Perception: 1d100 ⇒ 1
"Brother N'Keln, Brother Lanius. If they continue to press forward, perhaps you can both take them out as quietly and cautiously as possible."

Watch Captain Tiberion |

Raziel, I'll just let you use your fate point for a +10 on the roll.
The Blood Angel's pack fires righting him from the free fall in complete darkness. Rising through the black, you land upon the opening to the level of your brothers.
From what you can tell, nothing else remains amongst the living in the bay

Brother Lanius |

Lanius takes a few steps back, spinning the turbines in his jetpack in case they try and rush him. He would beat them to it, were that the case.
Readying an action: If they advance to about five metres away without Raziel showing up, activate wings of the angel and charge the closest one.
Wings of Angels vs: 1d100 ⇒ 86 Nope...
Charge vs 57: 1d100 ⇒ 40
damage: 1d10 + 3 + 11 ⇒ (5) + 3 + 11 = 19
tearing: 1d10 + 3 + 11 ⇒ (1) + 3 + 11 = 15
19 damage, pen 3.

The servitors immediately stop their advance, halting as if statues. Kill-safe protocol accepted, please identify life forms. The harmonic machine voices slowly repeat the commands.
Alright lads, you can try and plug in to interact with the servitors or continue on your merry way. The choice is yours
