[i][color=00aeef]"If our tech-mercenary makes a mistake, there is going to be one hell of an explosion."[/color][/i] thought Aviza to herself before motioning for her squad to retreat quite a distance back, [color=00aeef]"Remain here until she has finished, I do not want any more casualties than there has to be if Vala makes a mistake."[/color] Aviza was not taking any chances. In truth, if the explosives did go off, there was a high chance that the tunnel could collapse on top of them. 

While Vala was busy working with great entertainment and glee, Aviza decided upon something that had been in the back of her mind, [color=00aeef]"White Scar and Psyker Adrianne, each of you will take one of my hallucinogenic grenades. Adrianne, I want you to use your warp powers to teleport a live grenade into the most condensed group of heretics that are not using enclosed air systems on their armor. White Scar, feel free to use the grenade where you see fit, I fully trust your judgement."[/color] 

After [i]very carefully[/i] passing out the hallucinogenic grenades to the White Scar and Psyker Adrianne, Aviza approached Vala and inquired about her progress with the makeshift explosive. [color=00aeef]"How far along are you with creating the bomb?"[/color] The Sister of Battle wanted to get moving as quickly as possible for obvious reasons. She was about to open her mouth and say something about how she hoped the tech-mercenary was being extremely careful though was cut off as the sound of gunfire and the loud bang produced from a frag grenade going off, echoed through the tunnels. 

Aviza's HUD informed her that the sound had originated from the smaller tunnel to their right, the one that they were planning on taking to sneak into the heretics supposed base of operation and ritual site. After glancing around at each of her squad members, she spoke to the one person she wanted to join her at the moment, [color=00aeef]"White Scar, follow me, we are going to go investigate the source of that sound. I want the rest of you to stay here and make sure nothing else happens."[/color] She did not have to tell the White Scar to be careful, she knew that the large man knew exactly what he was doing and would be prepared for anything that came their way. None the less, she took the lead and slowly entered the tunnel with her Adrastus Bolt Caliver raised at the ready. 

What they found was unexpected, to say the least. Another human of the Imperium, this one dressed in rather odd clothes that made him stand out from everyone else in Aviza's squad, with exception to Vala of course. [color=00aeef]"Stand down immediately and report soldier, who are you, how did you end up down here?"[/color] said Aviza, lowering her weapon but keeping her guard up. She would take no chances, knowing that the heretics were crafty. 

The pile of dead heretics helped eased part of her suspicions though. However, she did motion with her left hand for the White Scar to keep his weapon up, it would be a very wise move for this new arrival to be completely honest with everything that he said, Aviza was not in the mood for any smart-ass remarks or any unintelligent comments. She had killed many humans who said they were part of the Imperium in the past, and would not hesitate at all to do the same here if this man made even the slightest misstep.
