At the same time, in the angels' realm, Heaven...
Just like the Underworld, Heaven didn't have continental barriers. However, the angel races had always been much more united than any other realm. All its Archangels, which was the title given to angels who had reached the highest realm, worked together with their own clans for the realm's prosperity.
At the center of all those angel races stood the city of Arcadia. By far, it was the biggest city in any of the realms, housing tens of billions of angels. There was no such thing as territories in Heaven. All locations were open for any angel who wished to come and leave, except for some specific places that the angel races considered very important.
