O planeta é chamado de "Ahch-To". O nome do sistema não foi revelado, mas como Tatooine está no "sistema Tatoo", Dantooine está no "sistema Dantooine", e Alderaan está no sistema "Alderaan". pode muito bem ser o "sistema Ahch" ou "sistema Ahch-To"
Do script WGA vazado:
EXT. AHCH-TO - DAY
A pristine and mighty OCEAN. Endless BLUE, dotted with random, beautiful, mountainous BLACK ROCK ISLANDS, dotted with countless GREEN TREES.
The Millennium Falcon FLIES INTO VIEW, BANKS towards one of the ISLANDS.
...
EXT. AHCH-TO ISLAND - STONE STRUCTURES - DAY
Rey arrives at a clearing. Small, modest, primitive stone structures. But no one around. Rey walks past them, sees, senses no one.
And then she stops. Feels something. She turns. Standing forty feet away from her, his back to us, is a MAN, in a CLOAK AND ROBE.
Rey stares, knowing exactly who it is. But she just stares for what seems like forever. Until he finally TURNS, SLOWLY, to her. Pulls back his hood.
IT IS LUKE SKYWALKER.
O Pablo Hidalgo da Lucasfilm confirmou este no Twitter :
So if you can see the WGA script, yes, the name of the planet from the end of the movie is there.
Como o faz Star Wars: O Despertar da Força: O Visual Dictionary , e - como pode ser visto nesta foto - Star Wars: A História de Rey :
Those words were still echoing in Rey's head as she flew the Falcon high above Ahch-To... Rey recognized the landscape from her dreams.
