Welcome to Fa'Diel

"Nine centuries ago, the Mana Tree burned to ashes. The power of Mana lived on inside Mana stones, enchanged instruments, and artifacts. Sages fought with eachother for control of these last remnants of Mana.
Then after hundreds of years of war, as the power of Mana began to wane, those who sought it grew scarce, and the world returned to peace.
After that, mankind grew afraid to desire. Their hearts filled with empty emotions, and grew estranged from my hands. They turned their eyes away from my infinite power, and were troubled by their petty disputes."
In the centuries since the Mana Tree was reduced to ash, the lands of Fa'Diel have become isolated from one another, as the people who populate the lands have lost all ambition, and have no need to leave their homes. If an outsider does appear, they are generally ignored, or short lived. Ages pass, but change no longer walks alongside time.
Should dreams and desire plague people once again, can the world be restored, or will it be reduced once again to ash?
