After their arrival, it was easy for them to find a Mansion. With the strength of their group, with majority being at the Noble Realm, it was already enough.
The addition of Collete and Tashirn make it so the possibility of getting a mansion into a certainty. And so, they found themselves in a Mansion relatively close to the Headquarter.
Relatively close as in it would take them 30 minutes of flying to reach there, as the nearest residential area, including the mansion they rent, is that far to the Headquarter.
Though, if they wanted to pick a Mission, they just need to go to nearby buildings called Adventure Post, where there are Mission Boards and group of receptionists handling the task of managing the adventurers coming in and out of the Adventure Post.
