i have tested this out myself with Cheat Engine. i could alter my own X Y Z coordinates and so i went ahead and skip the trigger of where you are suppose to get a clue about the whole invisible bridge thing(beginning of the game right before alisha) and you cannot talk to her, also if you advance further(outside to elysia) nothing is there as its suppose to like NPCs are missing and triggers. you can actually leave elysia no problem while normally you're stopped doing so.
Apparently and this is my assumption is that the devs went ahead and made an failsafe system where as if you start falling a certain amount it trigger that you are not in the blessed domain of a seraphin and teleports you to another location also shown in the video.
i don't know how to embed the video properly to make it show as an actual video instead of a link. in the video i go to various locations including every major town and even traverse the malevolence past camelot bridge.
as title says im gonna do a run on zestiria PC NG+ but someone in my chat asked if there are any loading differences between the versions.
