The Sovereigns are portrayaed as ruling over a quarter of the Digital World. This ties into the mythological figures that they are all based off of, which are all based on Chinese astronomy. Kyoto was chosen to be the capital partly because the four gods are in harmony surrounding the city. The mountains to the north are for Genbu the turtle, the river to the east is for Seiryuu the dragon, the river to the south is for Suzaku the phoenix, and the road to the west is for Byakko the tiger.

bio:Azulongmon appeared when Blackwargreymon tried too destroy the last destiny stone. The control spires in the eastern region were built too seal his powers. He’s 1 of the 4 mega digimon that preserve the balance of the digital world. Azulongmon planted his seeds of light to re-grow the destiny stones so the digital world would be balanced again.He also has pure digital powers (that look like little balls) that can make digimon digivole into ultimate level and apparently make Gennai look younger.
