The Royal Asthavon Palace

This is most likely a crown jewel within the depths of The Demon God's City. Atop one of the highest peaks of The Demon God's City awaits the manor in which the the most infamous and famous Royal Demon Families call home. All those from the Royal Asthavon Family will always have a place in this truly colossal fortress. In terms of size? It's roughly equal to a ten mile radius. So, in fact, it could also be considered a small section of The Demon God's City. It houses thousands of Asthavon Members, separating those who are aspiring to become ones in the furthest outskirts and away from most of the true and closer members of the Asthavon Family.

Not only that, but security around this place is almost air-tight. Some of the top class warriors that Demon World has to offer call this place home, there are royal security constantly on patrol and a barrier has even been eradicated that equals the Seiretei's own Sekkiseki Stone and the likes of Karakura Central's infamous force-field. Ergo, it is not wise to simply sneak into this place for uninvited guest.

Alas, once you reach the center portion of this Palace, you will find where The Sisterhood and The Brotherhood stay in the massive compound that is roughly two miles in every direction. Each member of these factions of the Asthavon Family are entitled to their own quarters inside of the compound, while those within Threshold are located in a "slightly" smaller manor that is estimated to be around one mile in each direction.

However, what seems to be most peciular is that there are three large masses of land that appear to rotate around the Sisterhood and Brotherhood Manors. Two of them appear to be blackened out, but the center one radiates an immense collection of Mana's presence and is perceived to be her lair of sorts.
