Jeddah, was Onderron in the Clone Wars cartoons. It must have been devastated from mining and climate change. But that is why I saw Guerrero was there and also the walled City goes back to the cartoon and before that the tales of the Jedi comics with ulic qel-droma from Dark Horse efforts to the Star Wars universe. Very cool.
Will (Whill?) Luke take Rey on a tour of the Jedi "planets" (like Jedha, Dagobah) and find some shards or pieces of relics, in E8? Does Chirrut's death comment to Baze about being with the Force mean Luke may commune with other Jedi (and Jedi followers) somehow, in that same film?
