This story is meant for a mature audience hence the mature rating. Eighteen and over please and if you are not please act like it.
I'm breaking farther away from cannon so this story can progress. That means the SSV Normandy SR-1 will be making its first appearance in 2177.
I'm also working on a different cross over involving star trek and mass effect (I know it's been done before) but I figure since I got the wild hair I'd do it.

Chapter 11: Discovery of a Beacon and Williams joins the crew.

Sept 04, 2177

Athena had spent the last few weeks training with her new unit. She noticed that other units gave hers a wide berth whenever it came out that the Immunes were around. She figured it was something to do with the way the unit was supposed to operate. She knew that the Immunes were an answer to the Citadels spectres and she hoped that they would never have to meet on the battle field again. Her attention was brought back to where she was currently sitting in the chow hall.

"Mind if I join you?" Kaiden Alenko asked Athena.

Athena looked over at Alenko before responding "What the fuck do you want Alenko?"

"I wanted to see who I had to fuck to get into the Immunes. I mean you got in so it shouldn't be too hard to join".

"Just go away and I'll pretend I never heard that. Don't want to embarrass you in front of your friends over their now do we?" Athena said while motioning towards a group of baby faced Marines.

Alenko placed his hands on the table and leaned over to get in Shepards face. "What the fuck are you going to do? If I recall correctly you and your unit got jumped by a bunch of bugs".

Before Alenko realized it he was sent flying over the table behind Athena. He cleared one table and landed hard on a second. He flipped off the table and spun around only to catch a fist to his face breaking his jaw. He staggered back from the hit before he had his legs kicked out from under him. Once he was able to finally see who his attacker was he was shocked to see a very pissed off looking Captain Anderson.

Athena was stunned to see Anderson beat the shit out of Alenko. She just sat there in disbelief for a few seconds before she jumped up to end the one sided fight. "Captain he's not worth getting passed over for promotion or a court martial."

"Wouldn't be the first time I've been passed over for promotion." Anderson responded before bringing his foot down on Alenko's neck.

Quietly Athena whispered so only Anderson could hear her. "Uncle David please stop I don't want to see you in the brig".

David Anderson turned his head to look at Athena before smirking and removing his boot from Alenkos neck. "Get the fuck out of here Pvt Pyle."

Alenko glared (or tried to) at Anderson before getting up and rushing to the hospital to get his jaw fixed.

Anderson watched him leave before turning towards Athena. "So do anything fun lately Shepard?"

Athena just stared at the Captain in front of her for a few seconds. "Well I just watched a superior officer beat the shit out of a former N7 classmate of mine."

Captain Anderson just laughed before telling Athena to follow him for a mission briefing.

"Um Sir you have to wait for the MP's to show up" a random Marine said surveying the fight scene.

Anderson pointed to a spot just above his left breast pocket. "You see this symbol Marine?"

The Marine just nodded seeing the Immunes insignia. He knew the MP's wouldn't stop Anderson from leaving. "Then what the hell am I supposed to tell the MP's when they get here?"

"Entertainment for troop morale" Athena answered for Anderson.

The Marine just stared at her with a blank face. "Fuck it I don't get paid enough to deal with this type of bull shit".

Both Anderson and Shepard started laughing at this and went to leave the chow hall. They saw the MP's finally show up and run through the door.

"Anderson why am I not surprised you're here. What happened this time?" One of the MP's asked.

"Nothing much just came to get my newest subordinate. Had to get past an ass hole to get to her"

"I'm just going to put this under super-secret squirrel since I'm sure you're about to report to Admiral Hackett anyways".

Athena had to slap herself to make sure she wasn't dreaming that an MP just let something slide. She then followed Anderson over to a waiting M12 light reconnaissance vehicle (warthog). "So any bets on the mission sir?"

As Anderson drove he filled her in on as much as he knew which was only that some Quarians had been attacked by a pro human group calling themselves Cerberus. This was the newest in a string of attacks on Quarians.

"Fucking really, they're our allies and a member of the SA. Which genius thought it would be a grand idea to kill our allies?" Athena questioned Anderson.

Anderson just gave her a navy salute (Shrugged his shoulders).

Once they arrived at Hackett's office they stood in the waiting room for a few minutes before the secretary told them they could enter.

Admiral Hackett was reading over the newest report regarding Cerberus when he noticed Anderson and Shepard enter his office. "I want you to find and capture or kill one Miranda Lawson" he said skipping the pleasantries.

"Wait that Biotic that follows Harper like a lost dog?" Shepard asked out loud.

"The very same, Intel has a suspicion that Jack Harper is in control of Cerberus but nothing solid yet" Hackett continued. "You'll be taking a new ship out for this mission. I'm just waiting for the top brass to authorize the new XO."

Anderson raised an eyebrow before asking who the new XO was. He was floored when he was told that it would be Shepard. David didn't think that it was possible to have two Immunes on the same ship one in command and one second in command.

Athena just let her jaw drop and for the second time that day she slapped herself. She almost didn't hear Hackett say that he would be taking them up to the Earth space docks to see their new home.

Sept 5, 2177
Earth Space Docks
Dock three

Admiral Hackett had stayed true to his word. He had brought both Anderson and Shepard to see the newest ship in the Alliance's fleet.

From what Anderson was used to seeing in frigates this one was different. "What are the ships capabilities?" he asked.

Hackett began explaining what the ship was capable of doing while walking with them towards the air lock. He thoroughly enjoyed the dumb founded looks on their faces when they saw Turians working on the ship.

To say that both Anderson and Shepard were surprised with the lay out of the command deck would be an understatement. They were even more surprised to see a few Turians walking around looking over data read outs on their omni tools.

"Admiral why are their turians here?" Shepard quietly asked Hackett.

The Admiral looked at her with a smirk on his face. "They are engineers that we rescued from slavers not too long ago. They chose to stay in Alliance space and offered to help design and build a new class of ship."

"I thought all slaver activity ceased when the SA conquered Khar'shan?" asked a confused Shepard.

"Not out in the terminus system. This brings me to both your new orders. The blue suns, eclipse, and blood pack are raiding out outer most colonies taking colonists." He began before turning to Anderson to issue him his orders. "Captain Anderson you are to take the Normandy out into the terminus system local and destroy any and all bases of the before mentioned groups. I'll have the forty fourth fleet send a small battle group to pick up any slaves, tech, credits, and prisoners you find."

Anderson gave a sharp salute after acknowledging his orders. "I'll have Shepard get to work on a crew sir"

Hackett dismissed both of the Immunes to let them get to work setting up a crew. He disembarked from the Normandy and almost knocked Liara over. "You okay Miss T'soni? You look like you've ran a marathon"

Short of breath Liara took a few seconds to compose herself. "I found something in the Prothean archives two days ago and I think you need to see it" she said before handing him a data pad with her findings.

Hackett took the data pad and scanned over the information before he frowned. "If this is true I'll need solid proof before I can bring this to the attention of the Alliance leadership."

Liara looked at the Admiral thinking for a few moments before conceding to what he said. She was also anxious to catch up to Athena since she hadn't seen her in a while. Not since the end of the Council SA war.

"Go on Liara if you hurry you can catch her before she reaches the lift". Hackett had not failed to notice that the young Asari was anxious and he put two and two together.

"Thank you Admiral and I'll look for more proof but please take my advice about preparing as much as you can." With that Liara ran off to find her favorite human not suspecting that she would be put on the Normandy's crew.

2180
Sovereign
Eden Prime

Saren sat aboard sovereign watching what was left of his force of Quarians assault Eden Prime. After it had come out that the SA had discovered a Prothean beacon Sovereign ordered him to acquire it to find out why the keepers on the citadel were not responding to his commands.

Of the ten thousand ships that Admiral Xen had started out with she had nine thousand eight hundred and ten left. She was not expecting to face an orbital defense platform with a super mac along with twelve frigates and a dreadnought. Xen hated to lose one hundred and ninety ships just too over whelm the defense forces and they still got off a distress call before her forces could make it planet side. Now it was just a matter of time before the Alliance responded and she hoped that with the alterations that sovereign had given her people they could get the beacon before help arrived.

SSV Normandy
On route to Eden Prime

Athena almost knocked over Cpl Jenkins as she hauled ass to the communications room to meet with Anderson. She shouted over her shoulder at the confused Cpl before running through a hatch that lead her towards the man she had been ordered to see. "Captain Anderson what's going on sir?"

"Eden Prime is under attack. Joker play the message again" Anderson ordered.

"One fucked up Quarian vid coming right up" quipped the pilot.

Athena viewed the message and was horrified to see Quarians gunning down Alliance Marines and citizens. Even their fellow Quarians were not spared. She then heard a female Marine calling for aide.

"We are under attack. Heavy casualties taken, we're not the only ones who know of the beacon. I repeat, rouge Quarians have come for the beacon. They came out of nowhere and-". The message stopped their when the reporting Marine was shot in the head by one of the Quarian attackers. The camera also showed an enormous ship that must have measured twelve kilometers in length.

"What the fuck is that thing? It's bigger then the nemesis class vessels." Spoke a very shocked Shepard.

"Get your gear and prep for launch Shepard. Joker get us in their fast and quiet."

Both Shepard and Joker sounded off with a yes sir and did what they were ordered.

Thirty Minutes Later

Ashley Williams of the two twelve had just witnessed her entire unit massacred by Quarians. What got her even more upset was the fact that even her Quarian friends were slaughtered like cattle by their own race. She ran firing blindly over her shoulder and was rewarded with a scream and a dull thud. Ashley didn't get much reprieve and had to duck behind a large boulder for cover.

This was the scene that Shepard saw when she cleared the crest of a hill. Not waiting for the enemy to see her she jumped down and raised her rifle letting loose controlled bursts that tore through the Quarians barriers.

Once the rouge Quarians had been dealt with Shepard walked up to the female Marine that was currently doubled over with her hands on her knees breathing hard. "Where's your unit Marine? Who are you?"

Ashley looked up to see that she was being addressed by an Immune and immediately shot to attention. "Ma'am I'm Gunnery Chief Williams of the two twelve. I'm all that's left everyone else was killed in the ambush that those fucked up Quarian rejects sprung on us. They came out of nowhere and even with advanced warning from the defense force in orbit we were still caught with our pants down. Especially when that huge ass ship landed and enemies started pouring out of it like cockroaches."

"Hey Tali, you have any idea who these Quarians are?" asked Shepard when Ashley stopped talking and took some water that she offered her.

Tali walked up with one of the rouges omni tool sifting through all the data she could. Her heart stopped for a second when she saw that this group belonged to Admiral Xen and were serving saren and someone named sovereign. "Keelah I wish it wasn't true but these Quarians serve Admiral Xen and two others Shepard. They belong to the group that broke away from the flotilla when we made peace with the Geth."

"What do they want and who are the other two that they serve?" Shepard began "If you can find out what you can about that ship".

"They serve a Spectre named Saren Arterius and another named Sovereign and they are here for the beacon. As for the ship, they believe it will help them destroy the Geth despite the peace between my people and them."

Shepard was already pissed with the surprise attack. Now she was furious to hear that the attack was instigated by someone she thought was dead and a bigoted Quarian Admiral. "FUCK" she screamed and punched the boulder to her right "Williams, where is the beacon located?"

"Just up ahead, we were getting it ready to be transported to the spaceport for pickup" Ashley responded.

"Lead the way Williams. Tali get on the horn and report back to Anderson with what you found".

A chorus of yes Ma'am shot out from both Marines before they headed out to where the beacon was last located.

When the group arrived they found that the beacon was gone and the place was covered in dead bodies of both SA Marines and rouge Quarians. Tali started removing anything she could gather information from. Once she had scanned all the rouges omni tools she activated one of her many programs to mine for any valuable information. "Looks like they moved it Commander"

"Williams on point get us to the docks assume all contacts from here on out are hostile", Athena ordered.

"Yes ma'am, I'm looking forward to some pay back"

Spaceport
Beacons location

Xen stood away from the beacon while Saren approached it and it activated. She watched as he was lifted in to the air by some unseen force and heard him grunt in pain. She approached him after whatever was holding him up let him go. "Did you get what you needed Saren?"

"Yes now set charges to the colony and make sure these back water vermin are wiped out" He ordered. Saren then turned to aboard a shuttle and heard a report that a group of two humans and a quarian were headed their way. "Stop them do not let them get to the beacon" saren yelled before disappearing with Xen on the shuttle.

The Quarians that were left behind set up the charges and an ambush to stop the Alliance's group.

Once Shepard and the rest of her squad arrived at the other side of the spaceport they were immediately met with a massive bomb and enemy fire. Tali started to disable the device before anyone could move. This left Shepard and Williams to cover her while she worked.

"Williams cover me I'm going to run across that bridge to the other side. Once is set up grab tali and follow I'll cover you both from that side". Shepard then jumped out of cover and darted towards the other side of the bridge.

Ashley popped out of cover and shot one of the quarians in the face mask killing them instantly. She then ducked back behind cover just as rounds started to impact around her. "How's it going Tali?"

"I just need a few more seconds" she responded. "There I'm done let's get moving"

Ashley radioed Shepard that they were coming across before she and Tali took off at a dead sprint.

Athena had just ducked back into cover when she heard Williams radio that both her and Tali were headed across. She primed a grenade and tossed it behind a container that a group of quarians were hiding behind. Athena smiled when she heard loud yelps of pain and dull thuds on the deck when it detonated. "Hurry your asses up I can see three more explosives".

Williams and Tali heard this just before they both slid into cover by Shepard. Tali saw the bomb nest to her commander and go to work disarming it.

"Did it strike you as a bad idea to hide by one of the bombs Shepard?"

"Shut up and fire Williams, we can discuss proper use of cover later"

They repeated the same process two more times before they arrived at the beacon. They saw strange spike like devices with bodies on them. Before they could react the devices activated and turned loose creatures that resembled humans but had tubes running along their bodies and their eyes were a sick shade of blue.

It didn't take the group of Marines long to figure out that these creatures where hostile and deadly at close quarters. One hit depleted their shields by half.

"Fire at will, kill all of these things" Shepard ordered while her rifle barked out in defiance of their newest enemies.

Tali and Ashley responded by bringing their weapons to bear and unloaded on the creatures until the dock was covered in the blood and body parts of their enemies.

"Bosh'tet" Tali screamed at the last creature as it charged her. She blew it back with a round from her shot gun before she relaxed when the all clear was given.

Athena radioed the Normandy that they had secured the beacon and didn't notice Ashley approach the beacon. The only warning she got was when she heard a surprised yelp. Hearing this she spun around and saw Williams getting dragged towards the beacon while she was struggling to break away. Not thinking about it she ran and shoulder checked Ashley way and was caught by an invisible force that suddenly lifted her up in the air.

Tali and Williams could only watch in horror as the commander was suspended in midair grunting in pain. As soon as it had started it stopped with the beacon exploding sending both Tali and Williams scrambling to catch Shepard's limp body.

The last thing Athena comprehended was Tali screaming over the radio for a med evac before everything went dark.
