The Dravanian hinterlands attracted students from all across Eorzea, and grew as a beacon of knowledge and wisdom. Yet this was not to last. In 1557, tidings that Garlemald had captured Ala Mhigo reached the city. To the Sharlayans, the Empire was a threat to their very way of life. They had spent an age stubbornly resisting all war, and the imperial invasion of Ilsabard and Othard was a bane to the values they had held since Nyunkrepf's time. Sharlayan sent ambassadors to Garlemald with entreaties to stop their advance. They even strove mightily to parlay a peace, but all these pleas fell on deaf ears, and the envoys returned home empty-handed.
In the wake of the failed negotiation, Fourchenault Leveilleur and the faction he led within the Forum elected to forsake their colony. Following five years of elaborate and painstaking preparation, the plan to evacuate the settlement's entire population to the northern archipelago of their homeland was put into motion. In 1562, the city of Sharlayan became a maze of empty streets and buildings in the space of a single evening.
