Castlemourn

Ed Greenwood, creator of the Forgotten Realms, teamed up with Margaret Weis Productions to bring about the Castlemourn Campaign Setting. A low magical fantasy setting featuring two new races. The Golaunt who are a mixed race of goblins, orcs, and humans. A cursed race known as the Thaele who are human in appearance, but very unsettling. As far as must know the world of Umbrara has a continent known as Mourna. The two moons Thelseene and Amaunt orbit around the planet, and in the starry sky there are 14 familiar constellations.

The worlds pastis mostly memory and the seven gods are silent on the matter. From what has been uncovered is that in the Ancient past magic was commonplace and even the humblest person could wield its power. Some 400 years ago outsiders from another realms invaded the lands Mourna seeing as it was rich with magical energies. These outsiders began to quickly take over various kingdoms, and soon the Great War began in which titanic magical forces were unleashed on both sides. As the battle waged the world of Umbrara was thrown out of balance as reality was rent asunder by the continual magic that was unleashed.
The world itself began to twist the arcane energies until a global backlash occurred. Instantly arcane forces ripped through the world, destroying kingdoms, leveling mountains and boiling seas. Those who weathered the storm found a changed world, and stranger still had no knowledge of what just had occurred. Their ancient past, the great war, and the memory of the invaders were all gone!

Since then the world has healed, and new kingdoms have arisen. Most fear magic, for strange things happen to those that come to arcane power (there lands may vanish, become altered, or come under the assault of an unknown magical force).
