On the world of L-532, there were six great empires. The greatest of these was Wyvern which held a massive fleet and a spread out Empire, during the turn of the century Admiral Kortiz Fek saw his chance and as the rival empires built older style 16,000 ton battleships with 2 pairs of two gun turrets, Wyvern introduced a much larger class of battleships with almost 23 knot speed, 8 12 inch guns, heavy armor and decent torpedo protection. Announcing eight new battleships would be built, the rival empire of Goren would declare war through a surprise invasion of Wyvern trying to use weight of numbers to defeat their opponents. However, the Wyvern coastal fleet would protect the main battlefleet as it reformed. The lead ship of the planned class, originally called Devastation until the ancient 11,000 ton battleship Thunderbolt was sunk with all hands sinking the more powerful armored cruiser Spear and defending a convoy in the process causing the Admiralty to rename the new battleship after the heroic vessel.
After nearly a year and a half of war, Thunderbolt and her sister Leviathan would emerge fully fitted and with the rest of the fleet engage the Goren fleet and destroy 8 of the 14 battleships involved thanks to a mix of heavier firepower and the battlefleet being broken apart as aerial machines carrying torpedoes emerged and while hitting no battleship would break apart the battleline allowing their battleship comrades to defeat them in detail.
After 15 years of active service, Thunderbolt would become a training ship for the fleet and spend the next 10 years in that duty before being torpedoed in the second war with Goren. Barely surviving, she was put into reserve as debate on what to do with her began. However, the war ended and Grand Admiral Fek managed to save the Thunderbolt as a museum. Nowadays she and the first carrier (The former Armored cruiser General Luten) Pioneer in the port city of Grewon where she first touched the water.
Just an idea I had years ago, don't know if I'll ever do it. Feel free to use, just DM me beforehand.
