This story is a sequel to Avatar: Legend of Diamond Tiara. Book 1: Harmony

Silver Spoon has embraced her role as the Avatar of Discord and Diamond has fallen... or so it seems. Is all hope truly lost? As the world of ponies and spirits begin to mix and ponies rise up to, once again, fight off the power of Discord, more questions arise and the true roles and destiny of the Avatar begins to take hold. Will this be the true end of Harmony, or just the beginning of a new world entirely? The final book in the Avatar series and the culmination of years of work, plotting and scheming awaits.

Avatar Diamond Tiara has suffered her first real victory, and in many ways her greatest defeat. Now she finds herself struggling to cope with the realization that she needs far more help than she ever thought. So she must turn to her old lives and, more importantly, Twilight. Together with her friends, can she discover what happened to her previous incarnation and, more importantly, the origins of the Elements of Harmony?

Following a speech at her old school, Twilight meets a young stalli... mare who wants to ask her a simple question. Was there a spell that could fix her and make her what she always wanted? Sadly, there is some things even magic and friendship can't fix.

The princess soon finds herself learning about a new group of ponies she never knew existed, while a young mare struggles with her own identity and being born in the wrong body.

Inspired by Eve Online(which I have been playing much too much lately)
In the far flung future, far from their home of Equestria, ponies and griffons have made four new empires to rage war with. With powerful ships and deep alliances, more and more they find each day a constant struggle for survival. For Ex, a slave with a stolen ship and no masters, he must struggle to find direction and escape his pursuers in a galaxy that doesn't care and desires to tear him apart.

Twilight was always fated to be the savior of Equestria, along with her friends. But fate can be so easily altered. What happens in one alternate realm when instead of marrying a unicorn, Twilight's mother had instead married an earth pony, resulting in her daughter being hornless? Without her magic, Twilight's future and destiny are far less certain, as is the destiny of all of Equestria.

However, destiny is not so easily set off course. When the princess of the night returns, can one little earth pony hope to be the one to help her damaged heart?

In an alternate human world, Octavia finds himself in a one week stand with the strange Vinyl Scratch after one of his concerts(after nearly breaking her nose). While initially annoyed at the idea, he soon finds himself absorbed into her life and, more importantly, her music. With only a week to get to know each other, will their relationship have a chance to flourish? Especially when he finds something he hadn't even known he was missing...

Humanoid Rule 63 Octavia/Vinyl ship fic. Enjoy!

While searching through the Everfree Forest for flowers, Cheerilee comes across a strange young colt. Foul mouthed, vicious and angry, the child is like nothing she'd ever seen. More importantly, he claims that ponies are like nothing he's ever seen. Could this little colt truly be something called a 'drow'?

At the same time, Rarity is preparing to welcome her cousin, a young filly named Silverbelle, to her home. However, the preparations are interrupted by a small colt calling her 'mommy' and of obvious draconic heritage. With three new foals arriving on the same day, could it all be coincidence, or is something far darker on the horizon?
