SIN ISLAND.
In between the Northern and Eastern seas, close to the Central sea lies an island. At one glance, it seemed to be just an ordinary uninhabited island. But on closer inspection, one could see that the vegetation of the island was bigger than the normal ones. And if you entered inside, you could see countless mutated bugs and animals which were much bigger and scarier than their normal counterparts.
This happened because the island was the closest island to Mythos Continent. In order to close the legendary continent, a powerful magical array was used. To support that magical array, a huge amount of Mana was needed. When that array was activated, that huge amount of Mana affected the nearby island. The plants and animals slowly mutated and as years went by the mutation just became more and more horrible until no human could enter inside without risking their lives.
Years and years later, the said island was known as Sin Island.
