Great story, so very unique.
I suppose in the next chapter we well find out if the whole moon was terraformed or just a small section.
What happened to those that supported him? You briefly mentioned Remus but not the others.
Also Dumbledore deserves more punishment! As for the Weasley's and Grange...seeing what he accomplished and being denied entry to their society would be enough. BTW was the twins in on the betrayal?
Hope to see more of this delightfully different story soon.
