Does anyone know where I can find this comic on Celestia and Discord?

I was browsing deviantArt the other day, and found this really cool comic series on Celestia and Discord. I've been searching today, but I can't find it. Does anyone happen to know what it's called?

It starts off with filly Celestia wandering the everfree forest, and bumping into Discord. They become good friends, especially after Discord rescues Luna. The story continues to them finding the elements of harmony and Celestia and Luna realizing their true duty to raise day and night. Discord becomes jealous and says,"Celestia, where is your sense of adventure?", and she replies,"Discord, you are my adventure."

That's where I left off. I never got to finish it, so if anyone can tell me what comic it is, that would be great!
