NOAH Report(sic): You wish to learn more about Syrcus Tower? Very well, let us review such data as we have on hand.
NOAH Report: The Crystal Tower is comprised of a multitude of spires. Rising high above them all is Syrcus Tower, the heart of the majestic structure.
It must be noted that the name Crystal Tower originated as a sobriquet. Ordinary Allagans coined the term, which over time came to refer to the collective structure.
Although the tower is referenced in various ancient scriptures, up until the end of the Sixth Astral Era, the scholarly community largely doubted its existence. Aside from Professor Erik, it had scant few proponents.
How is it possible that such a colossal structure could be kept hidden from mankind, and for so long? The answer was to be found amidst the ruins of the Fourth Umbral Calamity, which took the form of a great earthquake.
During the final years of the Allagan Empire, the lesser moon Dalamud harvested the sun's energy, which it then transferred to Syrcus Tower below. However, that energy proved too much for the tower to contain. It escaped into the land, causing the earth to collapse into itself.
In mere moments, the Allagan Empire was laid to waste. Yet even as the Crystal Tower was sinking, Emperor Xande's most trusted aide, the technologist Amon, invoked powerful magicks and halted the flow of time within the structure. The tower and its denizens fell into a deep slumber.
Three eras later, when Dalamud began its descent, the Crystal Tower stirred to wakefulness. Shortly thereafter, the cataclysmic arrival of the Seventh Umbral Era saw the tower returned to the surface.
The fellowship of NOAH ventured into the Crystal Tower, its first visitors in millenia. Awaiting them at the apex was Emperor Xande, the legendary founder of the Allagan Empire, who had awakened alongside his minions.
