Game concept
Entourage
From the game's encyclopedia
It's dangerous to go alone, so you should bring along some companions in your Entourage. Everyone who Travels with you is part of your Entourage and share in the challenges you may face on your journey.
Your Caravan Master is the leader of the Entourage and manages your travel plans.
Some Characters are added to your Entourage by default when planning to travel. Travel Options and Activity Options offer additional ways to add characters.
