The Borderland Ruins (Secure)

While many will remember the Calamity for the destruction it wrought upon the realm of Eorzea, that destruction was not without its blessings─one of those being the uncovering of ancient Allagan ruins hidden underneath the war-scarred Carteneau Flats and heretofore unseen for several Astral Eras. When an attempt by the Grand Companies of Eorzea to determine the control of these ruins, and more importantly the secrets they contain, through peaceful negotiations ended in failure, the city-states instead elected to solve the issue of dominion using a form of civilized warfare dubbed Frontline.
