Many years ago, a much smaller, and as such lesser known, island known as Arisu Glade suffered a series of tragedies that would bring it more renown, but not in a way that was good.
On this island, it was very common for minor, non-violent sacrifices to be made in order to bring in crops and rain, amongst other things. A certain group of people, however, decided that these were not enough to bring in satisfactory results. So, they conducted more serious and brutal human sacrifices, often against the victim's wills.
Sacrifices in such a way amongst the islands was considered taboo, and was why if one was needed, the islanders tried to keep it to more minor ones and if killing anything ever had to be involved, they always killed an animal. As such, the lingering, angry spirits of the sacrifices on Arisu brought bad luck and subsequently cursed the area, leading to the remaining inhabitants fleeing and causing the island to fall into a state of despair and death.
The island's former name is not as known now, with the better known Hitobashira taking its place.
