[@jasonwolf] Ancient Robots would require quite a bit of world twisting to make work. Ancient Robots need Ancient Flowers in order to function-- which would all be loooooong gone by the time we got to this timeline. The only way to possibly get them would be by using Timeshift Stones, which are incredibly rare. 

Tell me more about the idea you have. How would you incorporate an Ancient Robot with the current place in the timeline?
