Darkswords has launched a Caravan mini event in the Desert area. Once an hour or two (or three, who knows) a Caravan starts crossing the desert. It doesnt go very fast, but isnt either too slow. It will not react to people attacking it and will keep moving with its pace. Upon reaching its destination it will simply disappear. If you manage to "kill" or rob it by then, you are in for some good loot.
