Caravan is the fifth optional quest. It is acquired by talking to Dio at the Farm. The objective of this quest is to bring at least one of three pack horses to Sam in Kalm. They don't have a lot of HP so the player has to take care of the horses. One of the easiest ways to complete this quest is to load a pack horse into the Transport Turtle and teleport to Kalm, though this is no longer possible in versions 0.9.3 and higher. If all three pack horses die, the quest is marked as failed, though the game still considers it complete. Upon successfully bringing a pack horse to Sam, he asks you to bring the Delivery Confirmation back to Dio. Doing so will complete the quest and reward the players with 600 EXP and 1000 Gold.
The gold reward of this quest can be increased to 3000 or even 5000 if the player manages to get two or even all three Pack Horses to Sam. The reward increases by 2000 Gold for every additional horse. In order for the game to register additional horses, they need to be nearby when a horse reaches Sam, completing the escort.
There is also an entry in the Kalm News that alters depending on how far you are in this quest.
