The party begins where they left off. The decide to explore one of the stone stairwells that descend under the ruins of the castle.
Simon cast Light on a crossbow bolt, and Mick fires the bolt down into the passage. They go down the stairs, coming to an old cellar what was likely used to store food in the past. Mick lights it up with Dancing Lights. There are overturned shelves and other junk. At the far side of the room they see a door off its hinges and on the floor, in front of an opening.
Beyond the passage they find a rough-hewn passageway that curves. It is dark. Mick lights up the passage and sees three human shapes clinging to the rough walls and ceiling, moving like spiders. They are pale, skinny and sinewy, have stringy hair and wild eyes, and wear the remnants of simple clothing. The creatures squint as the light hits them and begin chattering and gibbering and laughing in a disturbing display of madness. Skittering across the walls and ceiling like roaches, they move quickly and attack the party.
One of the creatures bites Mick. The bite does a little damage, but also attacks Mick's mind. He hear's, in his mind, horrible shrieking and mad howls of tortured human minds, taking additional psychic damage. Each time the creatures are hit they simple giggle madly. The party kills these insane beings, and continues down the hall.
The passage opens into a large excavated cavern-like chamber with a 20-foot ceiling. Dancing lights illuminates the chamber, revealing human bones scattered across the floor, an area raised 10' at the far end and stone steps leading up to it, and in the middle of the floor a 3' tall stone cistern the apparently is full of water.
Mick walks by the pool on his way to the steps. As he comes nearer the pool his mind is assaulted by the feeling of dozens of minds screaming in terror and confusion. Debi comes up for a look and the same thing happens.
Suddenly Simon is confronted by a being that looks like the old man from his lucid dream. The creature attacks him. He fails a save and is paralyzed due to a mental assault in which he senses some familial connection with what is happening -- he is stunned and loses a turn.
Mick runs up the stairs. When he and Debi looked into the pool they saw clear water, human skulls sitting in the bottom, and thousands of undulating smoky black tendrils moving in the water in a complex web, constantly changing and shifting.
Simon regains his senses and casts Bless on himself and his two friends.
The party feels confusion and madness emanating from the pool. Debi sings and gives Bardic Inspiration to Simon.
Longer water tendrils rise from the pool and attack the party, ignoring armor protection and doing psychic damage upon hitting.
Debi is confronted by a creature resembling a mixture of her patron, Rax, and his pet, Magpie. The creature attacks her. Mick is confronted and attacked by what appears to be an undead version of his mentor, Blix Yodarian. The PCs see each other fighting non-existent enemies. Simon finally saves and the Phantasmal Force illusion leaves his mind. He blasts the pool with Guiding Bolt. The spell hits, and the party hears dozens of voices screaming in their heads.
More water tendrils attack, but finally Debi and Mick save against the spell. Simon attacks with Sacred Flame. Debi leaves the room (she has taken heavy damage), as Mick slashes into the pool with his magic dagger. He is surprised that it does in fact cut and damage the smoky black tendrils in the water.
Calling upon the power of Ahki, Simon calls down Sacred Flame once again to blast the pool.
The party hears screaming in their heads and each takes psychic damage Simon's spell destroys the network of magic neural tendrils in the pool in an explosion of mental energy.
Debi comes back in. The characters all feel a sense of peace replacing the background noise of insanity and confusion. They go up on the raised area and find record books which list the names of inmates in the asylum who were apparently used in evil magic experiments in this chamber. They find scrolls describing those experiments and the theories behind them. They put all this stuff in the Portable Hole and leave.
As they exit the stairs to the surface they find a gigantic blue saber toothed blue cat sitting high above them in the ruins. Clearly it is Bubastis. The cat slowly evaluates them. Each of them feel the cat's mind telepathically probing theirs. They converse with him. He says they have silenced the screaming he has heard in his mind for many years, and he is grateful. In thanks, he allows Debi to cut one of his smaller whiskers to complete her quest on the island, then tells them to leave without killing anyone else.
The party leaves, returning to their rowboat by the small dock.
