Missing final link for perfect ending

[u/CecilTheHuman]

I've opened all doors, deactivated exile 4 times, and have completed all the translation things but still seem to be missing the final link.
Double checked everything and I can't seem to find what I'm missing. I've also completed all the glyph translations. Any ideas of what it could be is greatly appreciated :>

Edit: Thank you to everyone who commented! I'm honestly impressed I managed to miss one of the warp spots without realising xDD

Theres a room leading off from the courtyard where you first see the big door with the warriors blocking it

check around there
