“

In the late Third Astral Era, when the ancient Allagan Empire was at the zenith of its glory, researchers toiled deep under the Crystal Tower to uncover secrets which might uplift their motherland to even greater heights. Their laboratory was dubbed Eureka Orthos, where impossible concepts of immortality, cloning, and dominion over the divine were made reality. So fantastic was this research that the legend of Eureka has endured through the ages, and now you have been tasked by the archmagus Noah to bring the laboratory's buried secrets into the light of day.
