Aiden moved as soon as he got what he wanted. In fact, he got more than what he wanted.
One of the three dungeons, the Draconic Wolf dungeon, was allocated for the exclusive use of the Hunters Guild. Only True Members of the Hunters Guild can enter that dungeon.
To give a proper example, Aaron is not part of any organisation. Though he has obtained a Hunter Card and can enter dungeons maintained by the Guild, those dungeons are not exclusive dungeons.
Though controlled by the Guild, anyone can enter the dungeon as long as they have the guild card, which is more like a permission slip. It doesn't make one part of the guild.
There are certain conditions that needed to be cleared in order to become a True Member of the Guild. This is true for almost every organisation present in the alliance.
Only when one becomes a true member can they enter their exclusive areas, which consist of not just dungeons, but ruins and other secret realms.
