The Giant never said that the gate is not actually a gate. There is nothing supports that in-story.
It's this thread's claim is that the gate is not actually a gate. There is nothing that proves that claim.
That begs the question why everyone called it a gate if it's not a gate. We're given no answer on that by the person who made the "it's not a gate" claim.
Three pages of discussion, there is still no answer.
And now people are discussing about Serini, again, for some reason. What a time to be alive...
