Can you replace a character who died, and can the group ever exceed four?

Question

Accepted Answer

You can recruit new characters while the group has fewer than four, but you can never exceed four and may not swap a living member out. New characters come from the Outside action (Visitor or Arrival cards) or from scripts. You do not get a replacement automatically when someone dies.
