Prince Eisen I class man-o'-war
Prince Eisen I was originally a war galleon of the Leovarran Armada, San Gabriella, captured in 1097 at the start of the Antara-Leovarra War. San Gabriella, an armed troop transport bound for Puerto Isabella (modern day Eisenburg), was intercepted by a squadron of three lighter Antaran brigs and sloops: Carida, Viper and Monarila. Surprisingly outgunned by the faster and smaller Antaran vessels, San Gabriella was repeatedly fired on, leaving her holed and her most crew and passengers cut down by wood shrapnel and cannon shot. Viper and Carida boarded the vessel to a surrendered and demoralized crew. San Gabriella was slowed sailed to a friendly port with escorts, however she was in such a horrid state the vessel nearly sank on several occassions due to flooding and had to be patched up along the voyage.
San Gabriella was put into drydock in Port Victoria, partially rebuilt and relaunched under the name of the current heir to the throne, in 1399. The same year as Prince Eisen I's relaunching, two galleons of the same design began construction. Up until then the Antarans hadn't had the vessel the size of the common galleon that the Aemoric powers fielded. The Prince Eisen Is, being a copy of a rebuilt version of an old ship, where of questionable value. These comparatively low-end man-o'-wars were no match for a battle line of the Armada. The fledgling Antaran navy was entirely outmatched and resorted to raiding transports and merchantmen as opposed to warships.
Prince Eisen I, pursuing a Leovarran convoy of four ships, was boarded and recaptured by an escort and once again renamed, this time to Nuestro Maestro Torio. Eisen's half-sister ships, Jacinto and St Katherine, would engage in battle with one-another in 1105, with St Katherine going down with all hands. The 1st Antaran Civil War shook the nation apart right after the end of the last war with the Leovarrans, and right as the other Aemoric powers decided they wanted a piece of the Antaran pie. Jacinto was captured by the Wesmeres the same year and renamed Undaunting. Undaunting's fate is unknown.
