Cincinnatus
It had been 50^5 years since Jonathan Shepard ended the Reaper Wars. So he did what he had done every day for the past hundred Millenia or so: he walked around the remains of the Citadel. He started in the crumbling ruins of the Embassies, It made sense, it was the first place he'd been. He paid his respects to all the races that had fallen, some to war, some to disease, most just faded away. There hadn't been anyone, of any race on the citadel for some-odd billion years. From there he walked around what used to be a lake, lost when the broke, 500 years after the last keeper died. As he got to the place where Apollo's once stood Jonathan Shepard sat down. He thought back to Billy and Joshua and Linda. He smiled, as he thought of how far they had come. A Kent on the council, 7000 years after Joshua had passed away, A Kent, discovering the means to keep Sol burning for another Million years... Ghost sighed a silent Sigh into the vacuum. As he got up, and continued his walk he passed by the remains of a New Mechanist forge, bringing back memories of the Union where humanity had finally managed to be at peace, and brought about the return of The Broken God. But even Gods can die with time. Except this one. As he wandered through the well beaten path, his feet falling into the imprints they'd made in the citadel floor Jonathan Shepard felt a buzzing in the back of his head. He leaned against a wall and closed his eyes, letting the signal into his Artificial Mind: The result of a 30000 year search, he'd sent reapers to every corner of the universe, looking for even a single cell of life. The results rolled through his mind: "Life Signs: Negative, Life Signs: Negative, Life Signs: Negative, Life Signs: Negative, Life Signs: Negative" a billion results a second scrolled by for hours, all of them nothing but "Life Signs: Negative" As the last result trailed off, Ghost opened his eyes, sank his face into his hand and slowly fell to the floor. He spent the next hour, thinking, millions of reams of data a picosecond, when he made his decision. He got up and walked back this quarters, where he, where he kept a small blue box. Jonathan Shepard, Saviour of Sapience, Eternal God, last living being, picked up the box and strode to the landing bay's remains. He paused as he remembered Anderson, giving him the Normandy. As he came to the edge of the strip he stared out into the universe, that once upon a time held promise of limitless possibilities, but was now just rock and dust and gas. He opened the box, and took out a small plastic medal "#1 HERO" embossed on it. Ghost Shepard Closed his eyes and put the frayed medallion's thread over his neck. As he opened his eyes The Prince of the Reapers gave one last command. And so, as each and every reaper in existence charted a course for the nearest star, Ghost Shepard whispered two words into the vast empty universe he had watched over for so long, given so much for as his systems shut themselves down, and he went, he hoped to see them, to see Josh and Tali and Kaidan and Ash and Billy and Anderson and Wrex and Liam and Cross and Aaron and Miranda and Gael and Amy and Jack and Joker and Klaus and Lucrezia and Liara and Linda and Joan and Tyler and Robert and all the others who he'd lost but, most importantly, to see Them again:
