Cyclops Harbor Cannons are immense artillery armaments. In 1458, the cyclops of Jolmgar constructed one that endured extensive test firing.
For an extended period following their production, Cyclops Harbor Cannons were positioned within harbor defenses. They were available for purchase to any individual possessing the necessary gold, and each sale included a seaworthy barge to transport the weapon back to the buyer's place of residence. With the growing prevalence of skyships, these armaments can now be encountered far from the coast, atop elemental motes, or in a variety of other remote locations. One such cannon has even been utilized by the dwarves of Hjalmarbrodd within the Underdark, with this particular piece, dubbed "the City Breaker," transported along a railway to engage their subterranean adversaries.
In addition to standard crew needs, a Cyclops Harbor Cannon necessitates the assistance of two giants or cranes with exceptionally robust pulleys to facilitate loading. The Giant Cannons, a mercenary organization, comprises the primary source for those desiring the services of giant artillerists. The majority of these cannons originate from the forge at Fjollaug.
