Thousands of years ago, there was a Goddess by the name of Oassia who brought forth life across the lands with her magical powers. Over many years life started to prosper bringing different life forms from neighboring lands to the city now called Oasis, named after the Goddess Oassia. Oasis used to be a desert land dry and stormy with no vegetation around for a hundred miles.
As time went on, different tribes started to relocate and over populate the lands. With over population came wars and bloodshed. Oassia had to do something to stop all the bloodshed from occurring. The Goddess decided it was best to spread her power amongst twelve different tribes. Special orbs were spread out around the land which have the power to bring forth life and or destruction.
Doing so Oasia had drained all of her power into creating runes which held these powerful orbs in place. It is said that the first two orbs were the light orb and the dark orb. Oassia died soon after doing so, leaving the people with these powerful orbs and a message that's hidden in the forest….
It took humans a century until they discovered that they would need to collect all 10 orbs to be able find the secret ruins buried with her message.
