Arimaspi Territory

The Arimaspi Territory is a mountain range located in the Farthest Reaches of the Mysterious South near a docking town on the South Luna Ocean. It's just south of the San Palomino Desert and the Macintosh Hills and the Caves of Conundrum. Unlike near by locations, the Arimaspi Territory appears to be rocky, rough and lacking in a forest. The tallest mountain is depicted as having a skull on top of its summit, though that may be an artistic choice by the artist of the Map of Equestria.

The land is presumably home to the Arimaspi.
