Summary
The world broke in the past thirteen years of Advent occupation; scattered remnants of camps, patrolling Advent units in the wild, groups of scavengers. It is clear to Luis, an ex-military survivor, that the world has truly lost its way. Alas, there is a certain wonder to the experience of consciousness, one that a viper, freshly separated from Advent, will not let go to waste. Truly, not fitted for another, both in species and in outlook. But perhaps beauty, some joy, and a little bit of companionship may just upturn the previous enemies' perception of the world and one another.

Summary
Two months after XCOM's victory and the fall of the Elders, a man continues to live in seclusion on his property, off the beaten path and hidden in the wilds outside of the formerly ADVENT-controlled East Coast Trade Zone. Isolated from society since the invasion and entirely on his own for the past eight years, his lonely life is disturbed by a wounded viper searching for shelter from her attackers.

Summary
The war for Humanity's autonomy is over, the alien despots of Advent have been overthrown by Xcom and a new age is on the horizon. However, world changing events do not occur without a price. Power vacuums were created in Advent's absence, their alien pawns, once completely under control, now have found their own autonomy, the land and its people are forever changed by their presence. All that's left for Humanity and Xcom to do is pick up the pieces, rebuild, and decide what to do with their former enemies. In a successful city state, located in territory once called the United States, a young man, from humble beginnings, does NOT have the power to fix ANY of these problems. To be fair, it's a big job, and he has his own problems to deal with. Life in the city isn't easy, everyone has to contribute, even him. And it's hard to decide what you want your future to look like, especially in a world filled with so many possibilities, but perhaps his new job will give him some direction. Will he be driven insane by the mundane environment and monotonous labor? Probably. But, will he also meet someone who interests him enough to pull him out of his comfort zone? You'll have to read to find out.

Summary
The Venom's Drip is a little hole in City 31's wall, and its owner, Zethra, has a comfortable-enough life ruled by routine. Unfortunately, one of her regulars throws her life for a loop, and she realizes she's nowhere near as healed as she thought she was.

Venom's Drip- Post Advent romance between Viper and Commander

Summary
For all its glory, City 31 is far from perfect. For all its technology and all its advances, it's still got parts of town just as rough as the old world. Something an unsuspecting man is reminded of when he takes a wrong turn on his way home at night.
Things don't exactly go great for him, but... maybe a bit better than he was expecting.

Summary
Gustave Wylder is a former MEC Soldier.
A deserter of XCOM who lives his life far away from any life he can manage, surviving off of scavenging, the occasional trade from wandering resistance or survivors outside of ADVENT's control. He's spent the better half of his days since his desertion doing everything in his power to stay off the grid and radar of ADVENT or XCOM.
However, just as the day he abandoned his duty, nothing stays the same forever. He just wished it didn't take him nearly breaking a few ribs to start the cycle.

Strangers in a Broken World by Edmar_Fecler

Summary
The war is over, the planet liberated, but much still lies in ruin. New clashes with old in distant battlefields, while most still struggle to get by. Isolation may be the best hope for survival, or should one be open minded of the new world? Who's to say.
Even so, humans are naturally social creatures, struggling greatly if deprived of companionship. Fifteen years of isolation would be enough to drive most men mad, for example. But then, perhaps Edmund was already mad? For why else would one be so acceptant of unseen things, waiting and watching from the dark corners of the mountain forests? What's a man to do when the shadows are the only real company he's had for such a long time? Resist the unknown, or explore and embrace it? It would be safer to avoid it, true, but perhaps he's been lonely long enough. The worst it could do was kill him, right? But then again, all actions have their consequences...
TL;DR A lonely man is being stalked by a Viper in the mountains. Stuff happens.

Summary
Five years after the Liberation War, a mission to extract a mole in the ADVENT Remnants goes horribly wrong. With the threat of traitors amongst XCOM's ranks, former operative William Mackenzie is pulled out of retirement. William enters into a world alien to the one he left behind, a world trying to rebuild from the destruction of the Liberation War and wipe away the taint of the Elders. He soon finds himself falling down a rabbit hole of terrorist plots, schemes and conspiracies in a secret war that could end XCOM itself.
And leading him into a new world is the only survivor of the failed extraction: a jaded, chubby, French-accented viper.

Summary
The war is over. ADVENT has fallen, and XCOM stands victorious.
But victory doesn’t bring peace, not really. The world is fractured, scarred by years of occupation and rebellion. Old systems have collapsed, and what comes next is uncertain.
In the ashes of conflict, survival remains a daily struggle.
A lone scavenger, drifting through the ruins of a recently attacked ADVENT outpost, finds more than just scrap and salvage. He finds a wounded Viper, one of the aliens who once served the enemy. She should be dead. He should walk away.
But something in her eyes lingers.
In a world where mercy can be fatal, one small act of compassion may change everything.

Summary
After the War for Liberation, City 31 stands against the odds. A tentative peace exists within its borders. But the war's closing battles rage on elsewhere, and scavengers continue to toil as everyone desperately seeks scraps of the old regime's technology in order to maintain some semblance of civilized life.
When a massive batch of fertilized viper eggs is found in an ADVENT storage facility, City 31 takes up the cause. Fearful that disposal would look bad to its non-human population, the city asks its resident vipers for assistance in raising the young.
Jia, a former soldier turned schoolteacher, considers the offer. Already familiar with human children and further enticed by the promised increase in basic income, she asks herself: how hard could it be?

Summary
You've been captured by aliens. Again. For the same reason as before, too! You've never been one to boast, but getting kidnapped for the sole purpose of having aliens use your brain for your strategic supremacy must earn you *some* bragging rights. This time the ADVENT's not going to have an easy time plugging you into their tactical mainframe thanks to the abundance of chrome and countermeasures installed inside your head, but the sexy slither of a certain snake monarch stands to test your loyalties. At least, that's the plan she's hoping to pull off with no risk of it backfiring on her...

Summary
Life in city 31 is unique, to say the least, being the only city to attempt incorporating earth's new inhabitants, brings in opportunity for unexplored interspecies interaction, newly formed cultures, and an impossible number of changes to the already tumultuous life of the post-invasion earth. Yet an equal amount of discrimination and the everpresent feeling of nearing conflict.
Throughout Nilian's life, he has had his share of alien and human bloodshed, now he simply wants to live out his days in this experimental city, contributing to the mixed society's health via his work at one of the leading hospitals.
One fatefully awful day, however, Nilian spots a particular female reptile, who soon challenges the human's expectations of himself.-
