From Labyrinthe Wiki
The Empire is divided into five regions: North, East, South, West and Heartlands. Eastwards of the Heartlands as far as the Xathrean Ocean is the East, or Eastcoast. Along this coast are the cities of Scarlene and Keys. Whilst techinically not part of the East, given that it is not part of the mainline Port Miere is often referred to as an East Coast or Eastern City.
