4277 	Over the course of three months, nearly a quarter of Kezmon's shipping is raided and plundered by pirates, resulting in a food shortage for the isle. Overlord Selantha again makes her offer to Kai Toka, and in a surprising public address, Lord Gursten accepts. With Tamzyrrian escorts, merchant ship losses become virtually nonexistent.
4317 	Increased piracy on the shipping lanes between Kai Toka and Tamzyrr causes an uproar amongst merchants in both cities. The famed pirate captain Bloody Malovor taunts the imperial government with his brazen attacks, gaining notoriety by sending any imperial soldiers and diplomats back to Tamzyrr in gruesome, mocking displays. Attached to each of the murdered messengers is a bloody cross over their imperial insignias. Unable to ignore such an open challenge to himself and the safety of the empire's commerce, Chaston is forced to focus his attention on developing a stronger navy for the Empire, which to this point had been largely unnecessary with the lack of a seafaring enemy.
4319 	The flagship of the navy, The Sea Drake, is sunk in a battle with sea raiders. Due to the increasing necessity for a naval force, Chaston postpones his designs on the lower DragonSpine Mountains, though a handful of mines begin operation under the protection of the imperial army. Over the course of the next century shipbuilding becomes a major source of income for Tamzyrr, rivaling the famed shipwrights of Kezmon Isle.
c. 4320	Battles with pirates between Kai Toka and Tamzyrr continue, with a few legendary pirates becoming very wealthy from their trade. As the imperial navy gains experience in combating the raiders, however, buccaneering dwindles. By 4328 the sea raids have become almost nonexistent, though Malovor is never captured.
4790 	Krolvin buccaneers land on Kezmon Isle and sack several small towns. The imperial navy responds and is victorious. In an act of defiant malice, the krolvin burn three villages that they have sacked and pour barrels of salt into the irrigation ditches before succumbing to the imperial forces.
4926 	An imperial expedition in the northern seas discovers the Krolvin Isle, homeland to the krolvin, and returns to Tamzyrr with this news. This is the first realization that the krolvin are a sovereign nation, as all prior contact had been with scattered krolvin pirates and raiders, and previous imperial expeditions into the northern seas had never returned. Empress Geleena Anodheles sends three emissaries to the isle, proposing peace between the nations. The emissaries are butchered and returned in pieces, and the empress declares war with the krolvin. 
Great numbers of krolvin attack the northern coastal areas of the empire, primarily Solhaven, Brisker's Cove and Wehnimer's Landing. Highland reiver clans aid in the many battles against the krolvin, battles that continue on for an entire season and are known as the Krolvin War. After their war-leader is slain, the krolvin are finally defeated and the bulk of their forces are driven from the continent. Only small pockets of the krolvin remain in remote areas.
