Session 25 - Isaiac's Maw

As we're about to descend down the stairs, we hear Raskin shout out for Ape from the other side of the house. As I start to follow Ape, Austar grabs me and we teleport to the main lobby. We then head to the garden greenhouse where we then see Malaphor attacking Raskin. After a few hits into Malaphor his possession is over. We regroup back in the main lobby and decide to go back to the secret door in the library and try and deal with Isaiac's ghost.
 
As we descend the stairs, we end up in a storage type room, and to the left behind us is an iron gate. We open up the gate and follow a long corridor into another small room with a locked iron door, which I opened with a set of keys found in the tower where the Boots of Moradin were. The door just leads out of my vision, we assume out of the manor grounds. We go up the spiral staircase which just leads to the ceiling. But I notice a slit on the slabs of the room and reach my hand into it and pressed something which slide the slab to the side, covering us in dust. I pulled myself up into the small crypt with the coffins we saw in the grounds of the manor.
 
We decide to walk down the man made tunnel which leads to an end, with a broken wooden ladder leading up 10 feet to some shrubs. We head back to the storage room, where I found another tile that seems interactable. I push down on it and the wall in front moves, and as I push on the wall, it opens up into a hallway. On the sides, it looks like there are cells, and at the end a metal piece of wall with a gargoyles mouth on it.
We send down Austar's skeleton summon down the hallway, and as it gets halfway, a small blue object beneath a sconce discharges electricity into the skeleton.
Austar and Raskin use mage hand to pull out the crystal below the sconce, when pulled out, the crystal dims from it's bright blue.
 
In the open mouth of the gargoyle head is a keyhole. Austar mage hands one of the keys from the set of 4 that I had. As he twists, the lower jaw clamps up, Austar wails in pain. Ape then tries a different key and the same thing happens. I then create water and freeze it in the keyhole to get a matching key, and then proceed to create a duplicate of it, but this time out of metal using my channel divinity. It thankfully works and we manage to open up the door. We appear in a room with a cell, and a desk with a skeleton sitting at it and an open book with small glowing purple runes and symbols. It shimmered and Isaiac appeared from the table and attacked us. I tried Dispel Magic on the book but it didn't do anything. I then closed the book but the front of the book has a strange metal star on it, on top of it is a large yellow eye with a vertical black slit and 4 smaller ones. Spreading from it a weird fleshy material spreading from the front to the spine of the book. As I closed the book, the large eye and smaller ones looked at me.
Around the skeleton's neck is a set of keys, and a silver necklace with a sapphire in it, etched around the sapphire is the letter 'D'. As I lift the keys and necklace, Isaiac turns to look at me and hisses at me. Ape runs over and shatters the skeleton at the desk which causes Isaiac's form to look less like Isaiac and more of a amorphous form.
I find a liquid vile in the chest and 50 platinum.
The liquid vile I find is a half full vile of Sovereign Glue.
 
In the tunnel, are eyes on the walls that when hit the floor rumbles and we hear a loud screaming coming from further in the cave. We head down the cave and see a giant maw in the middle of the room, and more eyes on the walls. The maw also seems to have creatures detach from itself and come towards us. In the ensuing fight, Malaphor goes down multiple times, Austar gets sucked into the maw and cut in two. Malaphor later on in the fight also gets thrown into the maw. Ape deals the final blow and I rush to the open maw and cast Healing Word on Malaphor which worked, and we grab Austars two halves and I cast Revivify which thankfully worked.
 
I identify the book with eyes. It seems reminiscent to a spell book, but where it's from and it's contents are alien to me. The schools of magic are not the same as the ones I'm used to. I'm fairly confident the book is not from this plane, if not further.
 
In the room is a bookcase with books lining them, as we read through them we discover they're Isaiac's journals.
 
The last book on the table I notice there are a number of symbols laced in the sentences similar to that of the spell book. The general gist of the journal talks about a fear for what he created, an inability to stop. Not being able to stop speaking and that he must seal his lips. "My fathers sovereign glue did the trick" and "I shall wear their skin" were the last entries.
 
We head through another corridor where we find a secret door to a wine cellar. We go through the corridor again and end up back in the main manor lobby and make our way back to the last tower we hadn't explored.
 
In the base of the tower we see some sort of building with 4 cauldrons with a viscous liquid. We go upstairs and I find a document that details how to construct a teleportation circle and some schematics which match the building at the base of the tower. The document mentions manor cauldrons, the liquid being melted opalizite. If enough is given to a teleportation circle, the usage of the circle can be used without a spell slot being needed when going to another teleportation circle, but the spell would need to be known.
