The Mystic Guild was still in its early days so, of course, everything starts off small.
The 100 people who got accepted yesterday had all woken up from a good night's sleep and gathered at the Guild Hall. There, they socialize, order food or just hang out if they want to.
The Guild Hall was huge, it's pretty much a large open space for everyone's use. There were also bulletin boards in there where several posters were pinned.
These are, of course, the mission that Guild Members could take should they need to earn Guild Points to exchange for the Guild's resources.
There are a lot of people who were already gathered in front of these bulletin boards, eyeing the missions in interest. Some missions required more than one person while others could be taken solo.
