Timeline stuff

The Mother Nature Arc (though Double Agent follows a different timeline):

Double Agent- story that alternates between Discord writing his autobiography and being a spy in Celestia's service
Kalopsia-Discord has nightmares about his ex, a dog god from the Amarezon.
Wanderlust- Discord leaves Ponyville to travel the world, mostly because he's running from his emotions.
Gallopagos-Discord tells Fluttershy a dubious tale of how he created the first Tortoise.

(Mostly) canon-compliant timeline:
Still Remains (The story I'm most fond of)-Discord struggles with the ability to feel, and ends up doing something shocking in order to do so.
Echoplex-More on Discord struggling with his ability to feel and accept reality. Luckily Fluttershy is there to help him through it.
Girl Talk- Discord goes to Rarity for advice on his crush on Fluttershy
Taxonomy of the Lower Reaches of the Discordian Dimensions- Discord doing stupid things to impress a girl.

Alternate Universe stories I wrote while angry:

With Teeth -Darker than I usually write. Discord's inner monologue about what he'll do to a stallion who hurt Fluttershy.

All stories I've named after songs:

Kalopsia (Queens of the Stone Age)- the definition of the word being "things looking more beautiful than they actually are."
With Teeth- (Nine Inch Nails)
Echoplex- (Nine Inch Nails)
Still Remains- (Stone Temple Pilots) though the meaning of the song does not fit the meaning of that story at all.
