A few other deities from various religions are thrown in as well, such as Takemikazuchi from Japanese myth, Loki of Norse mythology, Miach from Celtic myth, and Soma of Hindu religion. In Orario and beyond, the gods and goddesses reside above the world, with Zeus sitting at the head of the pantheon. However, some of the deities existing above humanity decided they would rather descend to the Earth to live among the children of the world they so loved. Though they are not allowed to use their powers on Earth without permission from above, many of the god and goddesses chose this more involved life over being worshipped from afar.

Familias in Orario are established by the gods and goddesses who sit at the head of a group of children whom they will support and lend their power to. These familias can have different purposes depending on the gods’ wills, though most of them have many dedicated adventurers at their disposal. Some familias can be quite large, like the Apollo, Freya, or Loki familias, while others only support a few loyal children, like the Miach or Hestia familias. The number of children that the deity takes under their wing depends on a variety of factors, such as their overall goals, how many people that god/goddess can support and, of course, if they even want to adopt that person into their familia.
