In the year 155, adventurers departing from Mechantus ventured into the Hive Region. Amidst ancient Auhtai ruins, they uncovered devices and intelligence pertaining to the advancement of sonic armaments. Dating back to the middle of the Horgon Era, these technologies were remarkably sophisticated for that historical epoch.
Today, Engineen's workshops are the preeminent producers of the weapons the Auhtai referred to as Päiki-Synhö; arms that employ sonic energy as their primary mode of attack. The Ba'lith Empire, situated closest to the insectoid components essential for manufacturing these armaments, is the second-largest manufacturer. Ba'lith's most renowned Päiki-Synhö is the formidable Knell Cannon. The largest devices constructed utilizing this technology to date are the imposing Sonic Horns along Ba'lith's southern frontier, intended to confront the ever-present menace of the Hive Swarms.
The formidable Päiki-Synhö armaments necessitate the utilization of carapaces and other components derived from specific beetles and bugs endemic to the Hive Region.
