Originally established as a colony by the Gaien Dukedom along with Razril, Middleport quickly became a prominent area of trade and commerce in the region. However, in 295, following the Gaien defeat at El-Eal and Kooluk's counter-offensive, Middleport quickly found itself under Kooluk occupation. While this stand-off continued, Kooluk forces on the island discovered that Warlock was conducting research into creating powerful Rune Cannons by utilising creatures from another dimension.
