Thank you so much for your support @carlgnash! :) The reason why I felt leaving the ending open was because I myself saw two endings. One where Lux destroys Earth and goes on traveling the stars, while Terra scrambled, saved some of the humanity and looks for a new home for them and with her assistance helps humanity thrive there and reach the greatness, eradicating all the terrible people did to each other, and the second one where they both decide that humanity will continue doing what they do if they left them there, so they destroy it all and ride to the sunset together. Pretty dark, I know, haha!
