Ezekiel [2]
The Straea Clan.
Not much was known about it to the outside world.
It had been mentioned before, but despite the grandiosity of their existence, the Straea Clan somehow managed to keep their internal structure hidden from the masses.
They weren't exclusive in this.
Void Palace was also quite mysterious to others. Their disjointed dimensional monstrosity of a palace made it difficult for anyone to get anywhere they weren't supposed to be.
On top of that, with how close-knit the people of the palace were, it was difficult to gain information from within.
However, since the palace was active in the world and openly showed its strength here and there, people were somewhat aware of its structure.
For instance, the 12 Swords were known in both name and appearance.
The Straea Clan also had their equivalent of the 12 Swords, but nobody knew who they were.
