The two interplanetary portals opened inches away from each other, magic and technology culminating in a set of coincidences that defy belief (or good writing). This isn't that story.

That was long ago. Trade, immigration, all things normal to relations have been established. The United Nations (backers of the Terran portal project) have come to be a real political force and semi-alliance between most western and modernized Asian countries much to the chagrin of the world's conservatives. The Triarchy of Equestria controls the other side. Things are interesting.

Aurora immigrated to Equestria hoping to start a business. One whirlwind of disappointment later she finds herself a personal maid to Equestria's lowest ranking and dumbest royal.

Unfortunately she has to stick with it. Fabricating a new identity for a human in Equestria twice is next to impossible.
