With a mighty heave, the doors begin to slowly open.
Beyond is a large chamber, 40 feet wide and 120 feet long. The ceiling is vaulted. The room is lit by glowglobes attached to the walls and suspended from the ceilings. Carved pilasters line the walls, and you can see alcoves extending behind them. The chamber ends in a set of broad stairs heading up.
The heavy doors take a few seconds to swing open enough for you to pass through, and another few seconds to open all the way.
As the doors are opening, Pwoolp, Vuoor, Solli and Rogoth can make out some faint voices in the chamber, but can't make out what they are saying.
As the doors are fully opened, three robed, hooded dwarves emerge from one of the side alcoves, 100 ft away. The robes are clerical vestments, and they wear religious symbols around their necks. They file out into the chamber, their bare hands pressed together in front of them in an attitude of meditative prayer. Without a word, they turn towards the party and start walking towards you, three abreast.
Their faces are hard to make out under their hoods, but their faces and hands look alive, though strangely pallid. They are not rotting, in any event.
Lady Miria failed to mention any priests in the tomb.
