Towards the end of the Mage Wars, Ebeta became embroiled in a brutal civil war, which destroyed the heart of the empire and left only a desolate wasteland. Shortly before the capital fell, a scribe named Julious emptied the palace library into three ships which set sail for the island of Crib, the last bastion of the Ebetan Empire. The books and relics eventually made their way to the Library of Arindell.
Ebeta was probably formed sometime during the late First Chaotic Period though its history extends back into the Age of Darkness. Its people likely descend from the Dear Clan. The heart of Ebeta was built atop the ruins of Cellious, a coalition of City-States which included Lahut. Cellious was destroyed in a massive conflict in the mid First Dynastic Period, and the Ebetans effectively paved over the ruins to found their own cities.
Ebeta was protected by several mountain ranges, and despite being only a few thousand miles from the capital of the Marcon Alliance, managed to avoid the Marcons. Historians believe a number of secret treaties between the two groups made this possible, though why the Marcons would uphold such treaties with such a small and easily-crushable foe, remains a topic of much debate.
By the end of the Dynastic Period, Ebeta was embroiled in a bloody civil-war, which eventually turned its once prosperous steppes into a high-altitude desert. This likely happened around the same time the old Oncar Empire was destroyed, although some historians argue that the Oncar were wiped out millenia earlier (Herbet Patric Galactis, in his Accepted Histories, posed that neither version of events can be known with certainty, and offers both chronologies as acceptable).
Immediately following the fall of Ebeta, the Rowens, who had endured a long fight for independence, erased the Ebetans from history. Practically nothing of their culture is still known, other than what can be found in a few dozen Ebetan books in the library.
