   Summary

   Harry Potter gets himself and his friends into whole new worlds of trouble when he stumbles on an artificial intelligence left under Glastonbury Tor by a long-dead Ancient being. The new paradigm this reveals to them leads his friends out into the galaxy and beyond. Merging magic, Muggle and alien technology together, they build themselves a new society. Can they avoid the mistakes of those who came before, both recent and Ancient?
