[sblock=OOC musings]This is one of the situations where not sitting around a table together makes life a bit more complicated as we can quiz the GM and have to rely on written descriptions rather than diagrams and or hand gestures

But we're not beaten yet, still a few things to try, and I love things like this in a game!
- despite having several spellcasters in the party there have been no divination magics fired off yet.
- nobody has tried either Knowledge:History in case there is a clue in the symbols (so Comprehend Languages and Read Magic are worth trying, as is Detect Magic) or Craft:Stone to see if there is something about the construction we are missing.
- even without any help from the above options, the symbology may be important. There was reference to people taking a coffin in. Can our religious experts see if the offering bowl/burial/eyes and scales motif is characteristic of a religion that might give us clues i.e. a type of offering required?
- @FitD: is there any significance in the word 'apparent' before the description of the coating of dust? Examine this 'dust' (making sure not to get covered in mold!)
- the doors are big enough for a mounted rider. Any Climbers in the party care to shin up it and see if there is anything above our current eye level?
- are there any other skills or spells we can bring to bear? So far our investigation hasn't got much beyond wandering around and making a few Perception checks. Disable Device seems like an obvious thing to try, anybody got a Knock spell?
Next 2 thoughts are:
- if the doors don't appear to respond to pushing then check the slabs in front of them - if there are any scuff marks on the stone, then they may actually 'pull' instead?
- they are reacting exactly as we expect huge stone doors to do, and thus could be an illusion. Is it a Will save to 'disbelieve' that they are actually there?
If it's neither of those, could you just clarify the description of the door when Sir Angus tried to push FitD. You said:
'
It is more of a solid slab of wall with a lock in the middle, but you get the feeling that it's separate from the main body of the giant pillar, and something like a (EDIT: PAIR OF) safe door(S): the lock is inside the slab, so no simple hinges.
EDIT: however, you can see there is a break between the doors and the pillar, but the mold has creapt under there. Also, the seam between the two doors is very fine. '
So it is a pair of doors, set into this huge pillar, with a very thin gap between them? Or is the gap between the edge of the door and the surround? Or both? One door has a 'keyhole' which we are currently assuming is connected to a locking mechanism on the other side.[/sblock]
