The Antramar Region is located completely underwater. Due to a massive catastrophe that occurred in the young days of Litvantar, the sea level rose and flooded many of the old land masses, giving rise to the current regions we see today. The land masses in Antramar were completely submerged, but this didn't stop aquatic races from inhabiting them.
The Demeri region has lain completely uninhabitable for many years. It is a hostile place where people come to visit and prospect, but never to live and stay in. It is said to have the highest concentration of raw magic, which is probably the reason why it is so inhospitable.
The regions that flank it are Garydi and Antramar.
