A/N: This is the first time I've published any work so please reviews and criticism are appreciated. The story is from a pen and paper RPG me and some friends made based in the ME universe, all OCs come from it. Shepard and his team will not be involved, just mentioned briefly from time to time. Starts at the Geth attack on the Citadel and takes place between ME1 and ME2 to begin with, may bleed over into ME2 but will not get to ME3 since I gave Hei Yui to someone else for their story. Without any further a due read and enjoy!

Prologue: The Bar

Hei Yui downed his beer in one long pull. He was drinking human beer, not to get drunk, but for the taste. He loved the taste of the hops they use to make it, would drink the stuff all day every day if he had the creds for it. Too bad he was finally drinking through the last of his haul. Damn Batarians, they said the humans were loaded, but their ship was worth more than the cargo it was transporting, and even that they had only gotten a few thousand for it. Last time he trusts what they say when humans are involved. He signaled to the bartender for another drink with a grunt, he was paid up for at least another ten beers and was going to make sure he got them. He glanced at the other patrons of the dingy little back ally bar he was in, noting that the Drell sitting next to him reeked of cop and wasn't actually drinking. He had what smelled like strong human coffee instead and it didn't even seem to have booze in it at all. Who goes to a bar to NOT drink? Gotta be a Drell thing. He spotted a Turian in the back nursing his beer and barely noticed the Salarian that was sitting off to the side. Sneaky little bastard just seemed to sink into the shadows in the corner and was just watching everyone….. Creepy as hell. Whatever, so long as they didn't bother him.

He reached for his newest beer when there was a massive boom and the whole building shook. What the hell? Alarms began to blare and the lights flickered. Avina's voice began to start calling out warnings of synthetics on the Citadel as a heavy metal door slammed down over the entrance of the bar sealing them in. "Synthetics huh? Heh Sounds like fun." He finished his beer and stood up, "Hey Turian, can you get that door open? I'm feelin like it's time to work off some steam." The bar keeper shook his head, "No can do Krogan, I'm not risking anything my bar or my life just so that you can have some fun." Yui just snorted, "Fine I'll just open it myself." He walked over to the door and leaned down digging his fingers in under the edge of the door and began to strain and lift throwing all his strength into it. The door groaned and then metal screamed as something gave way allowing him to lift up, allowing him to stare into the bright light of a Geths' head. It was kneeling in front of where the door was with an omni-tool glowing on its arm, a guard standing behind him waiting for the door to open. They both paused in surprise for a moment before the Geth went for its gun and Yui simply ripped its head from its shoulders. The guards head explode before Yui even got take a step towards him, the guns shot ringing out from behind him. Yui glared behind him to see the Drell lowering his smoking gun as he sipped his coffee, the green bastard hadn't even really looked when he took that shot. "The hell is wrong with you Drell, that was my kill!" The Drell took another drink of his coffee, "Didn't see your name on it." The Krogan scowled at him, he was looking forward to the fight. "Whatever, I'll just find something else to kill." Yui began to walk away but paused out of curiosity when he heard a notification noise from the Drells ear piece as he got a message, the Drell listened for a few seconds before nodding and standing up bringing his coffee with him, "Wanna do some real damage? I just got a message from C-Sec telling me where the real fight is if you're interested. Lots of Geth to kill." Yui grinned, "I might be interested. Even if it is for C-Sec."

The Drell nodded and glanced back as he heard movement behind him. The Turian and the Salarian stood up and moved up behind him as well. Yui glowered at them, "Friends of yours Drell?" He shrugged, "No but I won't turn down more help. I'm Drellius, Scooge Drellius. What about you guys?" The Turian looked like he wasn't really even there as he said, "Gogzurah." The Salarian piped out, "Sheldon Cooper." and all eyes turned to the Krogan. "Hei Yui." They glanced around to see who he was talking to before looking back confused as the hulking reptile glared down at Scooge, "Where we going Drell?" "The Presidi- hey where are you going?" Yui started lumbering down the hall and called over his shoulder, "To grab a car. What you planning on walking there?" The group glanced at each other and hurried after him, "Hey er you wait! Don't you want to know where on the Presi-" the Drell was cut off by the sound of gun fire as they rounded the corner just to run head first into a combat team of Geth that was standing around the rapid transit controls. The bullets slammed into the teams shields as they all dived for cover. All except Yui who left out a booming roar and charged head first into the squad instead sending Geth flying as he bulled into them like a bowling ball into pins, crushing bodies and tearing off limbs. Supporting fire from the team started ripping into the scrambling Geth as they struggled to draw a bead on the raging Krogan in midst and deal with the longer ranged gun fire from the rest of the team. In all the fight didn't last long though the Krogan emerged with more than a few wounds to show for it.

He didn't seem truly hurt by them though, instead his eyes gleamed with fierce joy, "Now THAT was a fight! Lets go find more." Yui walked over to the panel and glowered at it when it didn't show him the usually options, instead it showed seemingly random lines of code. "The hell Drell did you fuckers in C-Sec decide it was a good idea to lock down transit in emergencies? Get your green ass over here and unlock the damn thing." Sheldon rolled his eyes at the Krogan "It must be some kinda Geth encryption. We won't be able to use it, I certainly don't know anything about Geth programs." Scooge suddenly pushed past Yui, "I'll fix it!" Sheldon just scowled at him, "What do you plan on doing? It's not YOU could possible know how to undo it. I mean look, you're not even wearing an omni-" Scooge reached the panel and with a mighty flourish punched the display. Sheldon shook his head, "Like that would ever-" there was a small sparking from the display before an electronic voice piped out, "Please pick a destination." Sheldons jaw dropped and Yui laughed, "That's my kinda hacking! Comon lets get going, I don't want to miss out on all the-" a noise from Scooges ear piece and as he moved off to take the call a static filled message came over the rest of teams omni-tools, "Help! Were a medical clinic….under attack from the Geth… wounded…need help! I repea…"

Sheldon tapped out some code on his omni-tool before looking up, "Its coming from near by. In this Ward by the looks of it." Scooge came back over to them, "C-Sec just informed me that the Geth just captured an armory that's not too far by rapid transit. I told them that I had a team with and that we could handle the job." Yui perked up a bit, an armory eh? Sounds like his kinda place. But wait… that emergency call. That was a clinic. Clinics are usually emergency shelters too. Everyone goes to those in these kinda situations. This ward is full of Asari. They would go to a shelter to hide. Which means the clinic is full of beautiful blue Asari. And if someone big strong and brave went and saved them they would be oh so grateful… "We can't go to the armory. There is a clinic full of As- er civilians that need our help. Or I should say are attracting Geth to them like Varren to a fresh kill. That's going to be MUCH more fun than some armory." Scooge blinked in surprise, as did the rest of the group. "Er you don't want to go to the armor full of big guns?" Yui wasn't even paying attention, he just walked over to the car with images of grateful Asari naked in his hotel room to thank him for saving them all dancing through his head. Scooge just shrugged, and the rest of them simply filed into the car after him.
