Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Three brave individuals- a unicorn, a pegasus, and an earth pony- undertake the most perilous journey anypony has ever been asked to perform to save the most cherished thing in Equestria.

A tragic accident robs Jay and many of his friends of their parents. Seeing no alternative aside from a life on the streets and poverty, they enroll in the Conversion Bureau program to emmigrate to Equestria. When Jay finds out that his close childhood friend and crush, Chloe, is going as well, he takes it upon himself to win her affection before the end of their ten day stay.

An ancient manuscript written in Middle English, the only surviving artifact from long lost Earth, may hold the true reason for the emergence of Equestria, the very existence of the Conversion Bureaus, and the deepest secret of Princess Celestia herself.

This story is a continuation and expansion of 'The Conversion Bureau: Letters From Home', but it is not necessary to have read that story to enjoy and follow this one.
