Unironically, I mean. In your game, do you have an institution called "The Adventurers' Guild" (or something along those lines) where the PCs can rest up, get assignments, training, rumors, beer, etc.
This, but when you look at all those guilds and organizations as a whole they pretty much add up to an adventurers' guild only spread out all over the place.(In a homebrew setting ... There would be guilds for wizards and thieves, churches, mercenary companies, and many other organisations characters can join.)
