In this scenario you're looking for party members to go on with you on your next adventure. You've posted a sign on the wall of the local tavern and 4 people actually showed up.

These 4 have their own personality, backstory, ambitions and motivations. Your first step is to sit down with each of them one by one and talk to them. When you got to know them enough, you have to choose which of them you'll take in your party and will follow you in your next adventure.

In the mean time you need to find out who they are and what drives them to be on the adventure with you.
