Ishana was neutral, independent, self-sufficient, self-governing, concealed in a magic barrier lone island in the Atlantic Ocean. It was called the "safest place on Earth" during the Great Dark War. It was a home to the Magic Association and the Ten Sages. It is also the place where the Magic Formula and Arch-Enemy Event Weapons were created. It was designed as Magic City Number Zero "Ishana".
At the center of the island was located an academy that taught magic, alchemy and basic education. Its biggest purpose was passing down magical knowledge and skills to the next generation. Dormitories were also located in it. The most important building on its grounds was the Sanctuary (聖堂 Seidō), usually only accessed by members of the Magic Association.
Besides the academy, there also existed other facilities that provided basic needs, such as residences, companies, vigilance system and judicial system.
