Palisor

Palisor was the name for the 'Midmost Region' of the 'Great Lands' of Arda (the future Middle-earth) described in The Book of Lost Tales Part One.

According to The Atlas of Middle-earth, Palisor lay between the Iron Mountains, the Misty Mountains, the Orocarni, and the Hither Lands with the Sea of Helcar in the center.

History
Palisor was described as being the place where the Elves first awoke. It was described as a place where great pinewood forests existed and murmured with strange noises in these early days. The area would later evolve into the land of Rhûn, Rhovanion, and possibly Mordor and Khand.
