OK, first post, so hope I'm doing this correctly

I've cleared the Excavations and can't for the life of me work out how to get to the Burial Chamber. I understand there is a pillar puzzle room... But I can't actually find it!

I've literally wandered round for ages. There are 2 points where I can see a higher level, but can't work out how to get there

It's probably blindingly obvious

Any assistance gratefully received... I'm off to have another look

When I get lost I use the clarivoyance spell and select a quest elsewhere.
