If the envoy is killed during a battle, the contract will fail.
Once the destination is reached, the envoy will leave the party for several hours, then join back.
The envoy must be escorted back to the settlement where the contract was accepted.
10% chance: After meeting a shady man your envoy may get attacked by Mercenaries佣兵 and you can choose a side. Defending the envoy simply continues the contract, taking the deal will get you the bribe money instead and you get flagged as a betrayer by that noble house. (Shady Deal)
