Purge of the Sin Eaters: The Grand Feast Hall

Across the black crystal bridge and through the portcullis, you enter a large, strangely quiet banquet hall within the large tower. The heat hits you first, intense sweat-inducing heat from a massive fireplace already stoked up, giving strong light to the chamber. 

Dead center of the chamber is a grand feast table. 

The table and chairs seem empty, but when you start to look around, you catch something from the corner of your eye. When you look at the table in your periphery, you see the table is full of food. The seven chairs are occupied with people, but they are nothing but dead corpses. The feast of suckled pig roasting on a spit in the fireplace, the mead is flowing from the glasses and the gristle from the pork still hangs in our departed party goers mouths. A soup of cabbage, potato and leak is still warm... even the delicious aroma is in your nose. 

But when you look directly at the scene, the chairs are empty and the table is bare.

Standing off to the side of the table (and plain to see) is a pair of conjoined dwarf twins, holding a morning star topped with a spiked iron skull at the ready. They are frail and pale, seemingly lacking the strength to even hold the wicked skull shaped morning star, much less pose a threat to you. Their mouths are moving in faint sing song babbling, what they are saying is difficult to hear from this distance.

To your left and right, six stained glass windows (each showing different scenes), and a hint of a closed door can be seen to the left of the fireplace, hidden from view by the many large rafters in the chamber.

As you take in the scene, the portcullis behind you begins to close... You have enough time to escape yet, if you leave now.

What are you doing?

OOC: Any lack of detail above is due to a "what you quickly see upon entering" thing. When you post, could you remind me what treasures you claimed from the previous encounter? Thanks!
