This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Tired of Luna's constant nagging, Celestia agrees to give internet dating a try. Using the website www.notforeveralone.com, Luna helps Celestia go on dates with potential immortal suitors. Shouldn't be too hard to find true love, right?

You can make a suggestion for any immortal across any manner of genre or fiction for Celestia to date next. Just make sure they're immortal for it to work.

Updates every Tuesday and Friday.

Guest chapters for immortals I have not covered are welcome, since I won't be able to write about every suggestion someone has. Note that all guest chapters are non-canon from the main story, so there is a bit of leeway to them. Talk to me over PM's for any further discussion.

Thanks to my editors The Ponytrician and Garnot for all their help!

This story is a sequel to Project: Sunflower

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

Erin will need all of her courage, all of her cleverness and, of course, all of her friends to see herself through what happens next.

After a devastating Third World War, a planet nearly identical to Earth was discovered hiding on the other side of the sun. Desperate to bring hope back to a war-torn world, all nations united to send a manned mission to investigate the new planet. But when the old war pilot sent to explore it arrives, he will learn that there is more to this new world than anyone could have imagined, and that it holds some secrets that will change both worlds forever.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Oh, no! Shadow Decimus --a killer-for-hire-- goes to Equestria to assassinate a pony only to be changed into a burrito!

Whatever is our overpowered protagonist to do?

Written in under an hour. No editing and no revisions.

Celestia has been destroying the world with her barrier and humanity believes they have truly no hope left but as the most joyful time of the year approaches the children of the world send their letters to a man who can great any wish if they have been good. And they all have been very good, and so Santa has to lay down a Christmas beating.
Note The Santa for this story will be a combination of various Santas from many different TV shows and Movies.
We will be seeing Some Rise of the guardian Santa, Elfa Strike force from Code Name Kids Next Door, the nearly endless amount of elves and reindeer from American Dad's Santa, and many more. SO please enjoy.

Tartarus: the fabled prison said to hold all of the demons of Equus at bay.

Few truly know what lies behind the impenetrable doors Cerberus guards. Some say that it is a pit, infinite in it's depth and darkness, from which there is no return. Other claim it to be a hellish plain, filled with fire and pain and suffering, to punish the demons for their sins.

All of them are wrong.

Tartarus is small. An inescapable cell for a single prisoner. But the tales about it's purpose are not false.

For this captive human holds the key to unleashing upon Equestria forces which have not been seen for centuries, forces which predate Equestria by many an age.

And soon, he shall be free.

The Earth is still reeling from the effects of the Collision Wars against Xenolestia and her hordes of Newfoals, humanity having emerged victorious but a few million citizens fewer. Then yet another Equestria appears, but this time the humans are quick to cut off the head of the snake, capturing the evil Princess Celestia and imprisoning her. But something seems different about this Celestia...something almost friendly.

Can the Harmony and Friendship that Celestia has treasured all her life heal some of the scars left by her wicked counterpart, or do some wounds just run too deep?

They say revenge is a dish best served cold. I used to wonder, how cold should it be? Well, I know now. The sort of cold that comes from eternal night and being locked in stone for over a thousand years. The sort that comes from the only person you think you can trust betraying you.

The sort of cold that comes from a knife in the back.

The Moon betrayed me. The Sun entombed me alive. And they were going to pay.
