Eastern Engelain is the geographical location defined as everything south-east of the Great Plains, though it is sometimes extended as to include everything east of the Great Plains up to the elven forests, (but given the uncertainty as to where one land ends and another begins, some argue that there is no space for any eastern Engelain there.) It is bordered by water to south, east and west, though sailing west would make you reach Southern Engelain, whilst sailing east would make you reach the lands of Kal'sea. To the north it is bordered by the Great Plains.
Eastern Engelain is for the majority made up of the Seven States. They have their own creatures which cannot be found elsewhere in Engelain- the likes of the capcaun, vantoase, pricolici, strigoi and moroi. It is for the majority populated by human beings.
