This save will skip through the trials that it takes to encounter the main legendary pokemon that is related to pokemon sun.
You should spawn right in front of Solgaleo and should be asked to go back to where Solgaleo brought you.
This file is only meant for "Pokemon Sun." You should keep in mind that this file is here for whoever doesn't want to waste time just to encounter Solgaleo and just wants to battle him already. This file will skip to the "Solgaleo Scenario."
