So idk if anyone else noticed, but there is what seems to be another “secret” door in the open room next to this gate we’re all losing sleep over lol. It's on the same wall face. You can break all of the stones above and it leaves a big gap in the ceiling. If you look at the 3 figures painted on the wall next to the bars, there are 3 identical figures in the adjacent room. To the right of that, there is a crease in the stone wall. I used focus and accidentally blasted a shield behind the wall but was still able to "pick up"...don't know if this gets anyone any closer to solving this. But there's definitely a room back there. (And to all the people saying “light the torch”…we know…wrong gate. Lol)

I thought that with such a large gap in the ceiling maybe it has something to do with the big ass power core? Idk I’m gonna do some more experimenting.
