I've been busy at work on the event system for Raiders.
The events are purely optional, but it will provide a bit of a break from the regular sandbox activities of the raiding caravans and pillaging settlements - plus it will allow the player to visit some interesting locations, custom-designed for each event such as battle domes, sunken battleships, blood-stained cliffs, car henge, whale skeletons, and more.
Will of course continue to keep you updated.
