Grantebridgescire Fly Agaric Hallucination Challenge Solution! (AC Valhalla)

I felt confused the first times I attempted this. After looking up a solution I decided to record this for other people, in the hope it helps!
If you are also confused: the "signs" the game developers are speaking of, are the three gates behind the fire pyres. Hope you can see them in the video, when I'm standing in the middle.
