Just from hearing of the strange ranking system alone, Raze was pretty shocked. He knew other guilds did these types of things. It gave a reason for members to strive to rise up to contribute to the guild.
Positions gave people power, and it allowed them to help and guide those lower than them, giving them even further room for growth.
The thing was, this type of thing only occurred in guilds that had a large amount of members. The Dark Guild couldn't have been that large, and the reason was simple.
For one, it was an underground, secret guild. They didn't have a true base of operations, they also didn't have funding of any sorts. The regular rewards and prestige that individuals got by joining a guild wouldn't be achieved with the Dark Guild.
Then there was the biggest issue that was looming over their heads. It was the fact that the Dark Guild was to be kept secret, and the only way to do that.
