Originally used as a naval fortress by the Scarlet Moon Empire, Toran Castle was abandoned shortly after the completion of Shasarazade. Still, this prime piece of real estate right in the middle of Lake Toran became attractive to pirates who often tried to claim the fortress as their hideout. This didn’t sit well with the Navy who chased these pirates out after every skirmish. Annoyed at using the military for such trivial battles, Sonya Shulen summoned a zombie dragon to clean out the fortress and to scare away intruders.
Following the death of Odessa Silverberg and the subsequent establishment of the Liberation Army, Tir McDohl journeyed to Seika where he was instructed by Mathiu Silverberg to claim the castle as their new fortress. Of course, Tir and his party would need a boat to travel to the isolated castle. In Kaku, Tir encounters Tai Ho who agrees to pilot the party if he can win a match of Chinchirorin. As soon as the zombie dragon was defeated, Toran Castle officially belonged to the Liberation Army.
The castle underwent massive repairs as the population steadily grew. Some of the repairs included the creation of bridges to connect the castle’s outer towers and the fixing of floors that were previously uninhabitable. As news spread about the spruced-up castle, businesses became attracted to the idea of establishing shops within its walls and many dissenters of the Scarlet Moon Empire considered it home over the course of the Gate Rune War. The Liberation Army abandoned Toran Castle after the war and moved to Gregminster to oversee matters relevant to the newly-established Toran Republic. Although most residents also left Toran Castle following the war, some people like Qlon stayed to maintain the premises.
