Ahirangi Complex

The Ahirangi Defense Complex is a collection of fortified buildings on Xiang Island (island in the northwestern-most part of Sundeath Bay) that house the powerful, fabled firework cannons, invented long ago by the Oriental dragons. The Complex is Avalon's primary line of defense against invaders trying to take the capital Ourouboros from the west.

Component Sections
The Complex consists of several buildings. The most elevated structure (the Xiang Platform) houses the cannons themselves, while below are the ammunition magazines and chart rooms. The cannons can be moved and adjusted to fire in specific directions for specific distances, all of which are calculated by technicians in the chart rooms.

History
The Complex was commissioned in 153 BFA by the Grand Council as a location for a long-range defense system for Avalon. They wisely anticipated a war with the brutish humans, and wanted to be prepared in the event that any assailant reach Avalon.

It was completed in 128 BFA, in time for the Second Great War. It was christened Ahirangi, which means "sky fire" in the Maori language. The cannons at Ahirangi were supplied by a monastic-warrior faction of Oriental dragons known as the Yanhua Order, who were known well to be some of the best pyroweapon creators of the time.
