Ionia's introduction to LOL

Surrounded by a dangerous ocean, many allied provinces formed Ionia on a huge archipelago called the birthplace. Pursuing the balance of all things is the long-standing cultural keynote here, so the boundary between the material field and the spiritual field is also here, especially in the barren hills.

Although the magical power of this land may be changeable and the creatures living in it may be dangerous and magical, the residents of Ionia have been living a rich life for hundreds of years. Monks practicing martial arts, militia organizations in various provinces, and even the land itself in Ionia are enough to protect local residents.

But all this ended twelve years ago, because that year, Noxas sent troops to attack the new land. The endless imperial army raged in Ionia, and it took Ionians several years to defeat the enemy at a great cost.
