What if Anakin Skywalker lived after killing the Emperor?
gpt
Darth Vader rises when his mask is removed, the untapped Force Potential of his son feeding strength into him and repairing his lungs with the power of ha-er, love. Luke, shocked and more than a little confused, drags Anakin Skywalker onto a shuttle, leaving Darth Vader behind.

Upon landing on Endor for Ewok Mardi Gras, Luke lets two people into his confidence - his companions, Leia and Han. They discuss the fate of the Emperor's mailed fist, who states that while he cannot atone for his crimes, he is prepared to accept the judgement of his son, though he dislikes his friends - both for their lack of faith in the power of the dark si-er, Force, and the fact that he was an all-powerful Sith Lord for an enormous amount of time and isn't used to taking orders or being judged by anyone bar his Master. He's trying, though.

Ultimately, they decide: Darth Vader is dead, but they can't trust him. The triumvirate of Luke/Leia/Han decide to let him live, but insist he remain anonymous. Almost no records remain of Anakin Skywalker. He will briefly live on Coruscant, before moving onwards to exile or hermitude. In the trees can be seen a group of glowing blue ghosts. Obi-wan has his head in his hands as Qui-Gonn's quiet laughter echoes from within the Force. Yoda can be heard muttering "Bullshit, this is." before fading away with Obi-Wan. They're pleased at their final victory, but bother are adherents of "Death fixes every crime". 

Once the victory celebration is done, the rebels attend Coruscant. With the input of Anakin, the defences of Sate Petsage and Yvonne Isaard's plans are quickly quashed. The Rebellion takes possession, as Anakin prepares a file of everything he remembers - Imperial coreworlds, storeworlds, military codes and structures, hidden fleets, the Emperor's hidden retreats (That he knew of). The Imperial Remnant is on the run, retreating to Byss - and taking a number of nearby systems, ultimately creating a smaller, more manageable, considerably tougher Remnant due to force concentration. Raids allow them to capture shipyard facilities, which they strap (using ducttape) with enormous hyperdrives and move into the new core systems.

During his six months on Coruscant, Vader decided to take the surgical option that left him with a 50% chance of dying - the Surgery was successful, and left him oddly disappointed - a latent deathwish. While still primarily synthetic, he no longer requires his suit. He still looks like a cross between a warty eggplant and the Crow, though - chalky, pale, lumpy and the synthetic limbs that allow him to survive and maintain his strength don't look natural.

He bids goodbye to Leia and his son, with Han in the background wearing a special vest, one lined with thermal detonators. He's never learnt to trust the new Vader. Anakin sets off into space, promising to return when Luke finally sets up the new Academy he's talked about, and until them, will be seeking redemption.

He sets off into the void aboard a shuttle, to gather the scattered lore of the Force in the unknown regions. He leaves behind a Luke vastly advanced in certain aspects of his training, who, despite carefully examining everything he has learnt for the taint of the Dark Side, found none. He filters most of this through to Leia when he can, despite her being too busy to learn due to the frenetic pace of New Republic politics.

Luke eventually sets up the Yavin temples as an academy and leaves to seek students. Luke eventually returns with his first twelve students. He finds a prepared stash of lore - a number of holocrons, lightsaber crystals, ancient artefacts of Jedi masters, holographic text, a confused and Force Sensitive old man kept in a zero-tau capsule who wants to know where and when he is and an empty shuttle that returned some two months ago.

One evening, Luke follows a premonition into the jungle. After a long period of travel, he comes upon a lake - smooth as glass, with a dark temple squatting in the centre. Hopping lightly over the footstones slightly under the surface of the lake, he approaches to find the temple rotting - as though the weight of ages was bearing down. In the temple's audience chamber he finds a dark and blasted outline of a man and an incredibly amount of dark side resonance, the kind that results from the death of a powerful Sith. It is matched by the sense of peace that emanates from the corpse of his father. One fist raised in defiance, lightsaber clutched within, the synthetic limbs have shut down and locked with the death of their owner and his body slumps in their embrace. A light touch of the body blasts Luke with a vision - his father, wielding amounts of the Force that should be impossible, banishing a dark spirit that bombards him with dark side energy. They both expire at once. Back in the present, Luke decides to leave the body of his father in the temple as a memorial and returns to the Praxeum.
