The Siege of Home is the attack of the fortress Home by the Guado.
Prelude[]
An attack by Sin in Macalania transports Yuna and her guardians into the desert. After everyone but Yuna regroups, Rikku tells the others of a secret place in the desert called Home where the Al Bhed live. But when they find it, Home is under siege from the Guado.
Battle[]
The party arrives at Home but it is under attack by the Guado. Defeating fiends and Guado along the way, they make it to the Summoners' Sanctum at the heart of Home where they hope in vain to find Yuna. They are soon forced to escape via Cid's airship before he orders the evacuation and then termination of Home.
Aftermath[]
The party is able to escape with a few of the population aboard the airship, Fahrenheit. Cid uses the ship's missile pods to destroy the remainder of Home.
Although Guado casualties are unknown, they are presumed to be relatively high, due to losses incurred in the initial siege, and to Home's destruction with many of its attackers inside. Al Bhed casualties, however, must have been high indeed for them to abandon and destroy their one safe haven, though this may also be because of the simple fact of Home's discovery - with its location revealed, further persecution from the Yevonites would be a certainty, forcing the Al Bhed to leave regardless of the battle itself.
