In the beginning, the continents of Contera and Greaith were entirely separate lands. Weather by some higher cause or random coincidence they ended up colliding. Each respective god/goddess blamed the other and their differences proved too great to come to a peaceful conclusion. When they butted heads it wasn't long before the sentient beings that followed each god/goddess joined in and so started the "Great War".
Each Continent had it's own terrains and races.
Contera had rolling plains, deciduous forests, desserts and lakes. The races that lived there were Sprites, Fairies, Elves, Feathered Dragons, Imps and Nereids, and were protectors of the ethereal plane's magics. Magics such as Fire, Lightning, Air, Enchantment, Mind and Curse.
Greaith had mountains, grasslands, evergreen forests, and marshes. The races that lived there were Dwarves, Humans, Halflings, Elemental Dragons, Beastmen and Deamons, and were protectors of the physical plane's magics. Magics such as Water, Earth, Nature, Healing, Body and Dragonslayer.
As the wars raged on the Wastelands between the two lands many lives were lost. However slowly the gods and the people started to find similarities and understandings as well. When the gods decided that no more bloodshed was wanted they chose amongst their people a "Champion" amongst each race and gave them great power. Those champions went through the battlefields collecting followers and destroying their enemies. In but a few years it was ended, the war that had lasted past the memories of even the oldest dragon came to an end but the casualties were great.
To keep such a great misfortune from ever happening again they created, with the power they were given by their gods, a great fortress in the middle of the wastelands where they would meet and discuss ways to keep their people safe. At least once every ten years they would gather at the Tower of Regret and disputes would be discussed and settled.
The gods looked down and were proud of their people.
