They went to take a look at those that required a fee to join. Every table had a chart placed on it, and on the chart, they would indicate who the guide was, how many times they had entered Reaper's Valley, what the strengths of the accompanying bodyguard experts were, etc.

At the same time, they also wrote down the things that they wanted to do and the places they wanted to go. If someone wanted to go somewhere nearby or they only wanted to go in to buy something, they could join them.
