"In the quiet moments between battles, he would catch himself going into those forbidden if-onlys. If only they hadn't been on opposite sides of a conflict that seemed to grow more insurmountable with each passing year. If only he could forget the feel of her skin, the sound of her laughter, the way her eyes would light up when she spoke about her blue skies.
But he couldn't forget, just as he could never see her again. He had no choice but to press on, because that's what a good turian would do. And he clung to the hope that somehow, someday, he might find his way back to that turian…"

Summary
What if humanity had never made it to Mars?
In this version of their history, the resource wars from the 21st century spilled over into a full on Third World War, but those who survived managed to rebuild and eventually returned to space under sub-light speeds.
In 2157 a turian navy frigate is forced to go through an uncharted relay to track down and stop a batarian slaver cruiser. The same ship has been abducting humans from the Sol system with the Council none the wiser. Through the Charon Relay, the turians find the batarians attacking the third planet from the system’s star, and the First Contact War takes a new form.

Summary
The First Contact War ends with a whimper, rather than a bang, and humanity surrenders to the combined turian and asari forces.
For Commander Delilah Shepard, it's the beginning of the end. Tried, found guilty, and sentenced to slavery, she's sold to Aria T'Loak, where her life as a gladiator starts. When she meets Liara T'Soni, daughter of a powerful Matriarch, Shepard sees an opportunity. Seducing the young asari archaeologist, Delilah finds herself entangled in Citadel politics, assassination attempts, and a budding revolution.
As she starts to fall in love with Liara for real, Shepard discovers evidence of a vast conspiracy. Together, they must find the truth — or face the devastation of the entire galaxy.

Summary
“The first words they say to you are tattooed somewhere on your body.” Shepard explained.
Garrus blinked, his subvocals pitching in disbelief. “That’s… so inefficient.”
“Alright, how do Turians find their soulmates?” She demanded.
“On the civilized side of the galaxy-“ she gave a rather undignified snort, “we find our bondmates through song.”

The Council has called for a peace summit following the disastrous First Contact War but neither side seems ready to make amends. It's up to Shepard and Garrus to bridge the gap if their fated romance has any hope of blossoming.

Summary
Rushed to hospital, it turns out Lt Hackett's injuries and bloodloss are serious.
This can be read independently from, or together with, The Scar.
As the title suggest, this piece wraps up the aftermath of the Scar; one "high-risk mission beyond Sol system" (as it is said in the Codex's Hackett-bio and re-imagined by me, the author).
POSTED August 13 and revised the 14th for a smoother pacing.

Summary
“Year ’57, post relay incident over a stretch of dead space just outside a high-density asteroid belt. Doctors studied the case of a sole survivor discovered in the wreckage of a turian spacecraft.”
“Reports say the soldier had spent precisely 82 days floating through orbit. With no radio contact. No comms. Severely wounded from a head on collision with an enemy fleet. The turian had resisted all initial attempts at extraction. According to the soldier there had been another survivor onboard after the initial crash. A crew member of the enemy’s ship..."
"...A human.”
An AU on why Saren hate's humans so much. What if that feeling had once been something else entirely?

Summary
The Alliance is losing.
For the last three years, humankind has battled ceaselessly against the turians, an alien fleet that launched a brutal war after humanity discovered ancient, forbidden technology. Despite humanity's best efforts, they are perilously close to all-out nuclear annihilation -- or a slow death by starvation as the skies burn and human colonies go dark.
Desperate for survival, the shattered remains of the Alliance's best undertake a mission with impossible odds: plant a bomb on the turian homeworld and end the war once and for all. But when the mission goes catastrophically awry, Shepard finds herself stranded in hell: a planet covered in the wrecks of a thousand starships; a planet that orbits a black hole. A planet hiding a threat far more ancient, and far more dangerous, than the turians.
And she’s not alone.
