Just an Idea, not sure if its been done before,
But how about a weekly market in Hydlaa, where crafters could sell their weapons and repairs could be made, people could sell food and drinks, diamonds, mushroom ect. Also this could be a good time for the newspapers to sell their papers or Guilds to make announcments ect
This could be on the weekend, where most of the Players do not have work or education to go to (Sunday perhaps?)
It could be a social event,where Players could meet new people. Which could be organised by the GMs or the players themselves
Well just an Idea
