I understand that in the current state of the game we can do mail deliveries as given by town criers to make a little extra gold on the side if we don't quite feel like killing or crafting. One thing I would like to see that I enjoyed in ultima online both on private shards and on OSI/EA were the NPC's in towns that requested to be escorted to other towns. Like maybe there is a mage In Resolute that needs an escort to Harvest etc. This would be another repeatable quest like the siege quests.
This would be a nice extension of the companion feature; temporary npc party members outise of just a single scene. Non-combat, so you need to protect them, but hopefully not dumb as rocks so you actually can.
