I have a few ideas but I am unsure of their success rate given I am unsure the stability of what we have left the work with or how this island truly even works.
I am under the impression that there are still overseers. We have slain one Man but were there not two women, as well?
Additionally, while the Force and 'magic' alone may not be enough, I have considered building an engine. I realize this is the most time consuming of answers and likely will not provide the solution we seek, but if we can create engines that push ships the size of planets through space then no doubt we could create one to rotate a planet. I simply require the man power and materials, which will be the difficult component.
