It was an unfortunate fact, but the Devices were so powerful that they would inevitably warp time and space, and end up landing on some backwards planet, and then we'd have to track them down once they discovered and used.
But this time, when we arrived, we didn't find a warlord ruling over a blood-soaked empire, but a society using the Devices to generate free energy, copious food, and so on.
We still have to take the Devices back and destroy everyone and everything around, but it was a nice change of pace not to have to fight too hard.
