[Lucy's POV: ]
The Adventurer's Association was a place that every person seeking freedom, experience, treasures, riches, and strength visited to start their journey and officially get recognized as an adventurer.
And, practically any adult or one with a recommendation from an experienced adventurer could become an adventurer.
Yes, one would have to go through some tests but they are mostly to test their strengths and abilities and give them an appropriate rank corresponding to their measured strength.
'There are guilds and stuff that's present in most of the fantasy MMORPGs, but it is just as everyone might already know about.'
The association though, was a central organisation. Calling it a global organization would also be true in this planet's case.
