In the decades since the Eldritch War, the Seasons Calendar has become the communal way to mark the days, no matter the race or origin of those that call the world of Isekai their home.
Centuries before even the Divine Races of Isekai would set foot upon the land, the gods found themselves divided by their tenets, choosing to fall in line with those others that shared their thoughts.
The large Kingdoms of Isekai agreed upon a standard trade for the value of metals. This allowed each area to mint their own coins with images and historical icons but still have them be useful during trade during travels to far off lands.
For many millennia, the Witches of Isekai were heavily persecuted, often being harmed due to their type of magic. The number of Witches was decimated, leaving only a few hundred remaining.
