Its all in the Cards.

Eye of the Storm looks at Briar with confusion after he realizes she's addressing him.
"Wha? Rose? Did you take a knock to the head? Beats if I know, This is something city-people do."

After making that comment, a memory flies into Rose of the Storm. They explain that they kind of remember that each of the stone slaps is sort of like the doors to each of their families crypts. They can't remember which crypt belongs to whom...

Having followed being her/his sister-companion, AlyThorn is eager to help as they realize this is nearing peace. "I can help here! This body feels really strong, I think I could even do three pushups!". With that, they walk up to the panel and press it.

Try as they might the two of them can get the stone slab blocking the doorway to move...

Realizing she went to the wrong door, AlyThorn goes over to the green door and tries to open it.

With the three of them working together they manage to pivot the slap and open the door way.
The stone slab is etched with the name Thornboldt Durst. The chamber beyond contains an empty coffin on a stone slab...

"That’s ominous." The room
Seemingly empty, Ashtar didn’t waste time, and moved on to the next doorway.

Working together, the trio slid the next slab open.
The stone slab is etched with the name Rosavalda Durst.
The chamber beyond contains an empty coffin on a stone slab.

"This is... unsettling." They'd found both the children's coffins. "Rose, Thorn. These coffins look like they'd make good resting spots for you. Put your bones here, you can rest, and never be bothered with any of this ever again."

The fairy nods sadly and waves over the tabaxi. "Come, let's put you to rest. While waiting for Eye of the Storm to come over, Briar starts to craft two more mini-bouquets of white flowers, full of roses and tulips, lilies and orchids, accented with lavender and baby's breath.

Eye of the Storm and Alyria both remove the small wrapped up bundle of remains from their packs. Going to the correct coffins the each carefully slide the lid open and lay the bones within.

Both of their bodies go briefly limp and their mouths open into a silent scream. You see a spectral mist pour out of their mouths. The mist forms into the ghostly shape of the young boy and girl. The ghosts both smile, wave, and then evaporate into nothing...

Ashtar watched the scene with a melancholic gratitude. He smiled sadly and waved at the ghost children, then waited for his companions to return to normal.

"That must have been pleasant. Unless any of you wish to inspect the crypts, we should move on ahead."

Eye of the Storm shuddered as the ghost left him, restoring his mind to its proper state.
"GAH! That was. THAT WAS AWFUL!"
He stepped back from the crypt, brushing his clothes as if he was still covered in something before taking a few deep breaths.
"Gods, I need to get out of this hellhole!"

With the group back to their normal senses the head down towards the next room.

There, they find a muddy dining room. This room is nothing like the lavish room filled with delectable goodies.
This table is laden with a grotesque feast of cannibalistic delights. Scattered across the old wooden table, you see a plate with a half-eaten human-sized brain; a larger bowl has a ladle and is half filled with floating eyeballs in a thick crimson liquid; on a wooden slab, there are a handful of human hearts, one of which has a carving knife stabbed in it; and a myriad of other bits of long pig.
All of the food is festering with decay and infested with legions of insects. The putrid aroma of rotting flesh hangs heavy in the air, mingling with the sickly sweet scent of decay. Gnawed bones and scraps of human remains litter the floor, a macabre scene of carnage and depravity that sends shivers down the spine.

When the party approaches the table the swarm of insects become agitated and attack...
