Mourning
These lands were once known as Tyrranth, a province of the Deathless Empire.  Long abandoned, Tyrranth has remained a lawless frontier for centuries.  All contact with the rest of Aerynth was lost at the Turning, and the factions of Tyrranth have battled for dominion ever since.

Redemption
This region is properly known as the Dalgoth Marches, named for the city of Dalgoth.  Dalgoth is the seat of the Holy Patriarch, and the city serves as the center of the Holy Church's power on Aerynth.  The Turning cut Dalgoth off from the rest of the Church's dominions, and unrest plagues these lands.
