"Ooo potato-leek stew, prefer turnip'n'tater'beetroot myself, but that could be useful" Weneon seems disinterested in the rest... For now

<We never really got a chance to establish this, but Sylvene is the name of the leader of the wizard barrow in the previous adventure whose disappearance left the barrow unable to thrive in her absence.  You're in her old house in Waterdeep right now.>

Marlyth will pull out a Torch from her Backpack since she feels that everyone might need the light to read the texts. As a result, she will snap her fingers together to create a fiery spark by casting Druidcraft and kindle the torch. If someone is still left behind or stuck somewhere, she attempts to assist him by providing illumination.

"Was the fifth corridor trapped? I assumed that was the case. Sylvene clearly didn't want any intruders to get access to her journal."

She fails to read the instructions of the spells listed on the vellum pages, and lets other examine it's contents.

(ooc: Calner tied his medallion and any others? (not Vrah's but whoever originally had the other one) to a rope and passed it back so others could get through area 2 without maybe getting hit by lightning)

(ooc: who has each of the 3 medallions now? where are they?)

Calner asks the group, "Is this book interesting enough to abandon our quest for the barrow treasure?"

After a sufficient pause to allow responses, "And can we get back there with the teleportation circle?"

<I think the point of the barrow was to learn some stuff abou the wizards, which led you to the home of their leader where you found a pretty spellbook with a 🔑 in it, so a burned out hobbit house is maybe not so  important in rhe scheme of things...>

Quote from Wile_E_Coyote >>That compartment holds an ivory key etched with sigils about the length of a human hand

<I wonder what's up with that.>

<as a player I do too.>

Ok, Angus will reach into the book and remove the key, and .... trace the sigils with his finger? *shrug* Look around for something else with the same sigils on it?

The handwriting has a practiced, careful style. It often refers to “my island” and mentions a “hidden page” there to keep the author’s thoughts and secrets in order.

Notes vary between addressing a reader and addressing the author. This journal probably wasn’t intended for any audience except the author herself.

The book also fully identifies and explains how to use the planar key, that it cannot regain charges, and that “to return to this world, seek the island’s keepers, for they can send you home.”

Planar key details:

*this key has 1 charge remaining 

"Teleportation Circle? So, you can read the spell instructions, Calner. I wonder what these other two spells say. Can you read this spell scroll too?"

Marlyth declares while showing a Spell Scroll to the Sorcerer companion that she had been attempting to study for a while. She suggests that the party should keep the Book for further inspection and must leave the trapped place.

"What does this key do, Sir Angus? Does the key has something to do with the spells?"

Intelligence: Arcana 15

"So what's the plan? Are we going back out?"

Marlyth will show Calner the Spell Scroll which contains a spell (6th Level: Otiluke's Freezing Sphere).

"We can take the path that had led us here to get back to the abandoned Townhouse, then we might be able to examine the teleportation circle. Finally, we can decide what to do with this key."

<You guys know you're just in the basement of the townhouse, like, under it and maybe a hundred feet from the secret door. It's just in the other side of the wall and through the hall of mirrors.

Also, you should probably just like use the planar key the book went on and on about.  This is an on the rails adventure. I'm not going all sandbox.

Hey, who wants to guess the :color: of this part? First right post gets a trinket.>

Angus declares, "Comrades, this magical key will open a portal to another plane of existence.  I suspect the mystery of the red wizards leads us that way.  However, a warning, this key offers a one-way trip only.  We must find our own way back to this world."

Guessing because blades, equipment and the need for "vigilance" that this is white (or colorless)

I don't play magic, so those things you listed don't strike me as white, but... Yes.  Chapter 2: The Hidden Page.

You find a Golgari Charm

When you activate this charm, you can cast the dispel magic, false life (3rd-level version), or stinking cloud spell. The charm vanishes after you activate it.

(@Brian_Avery, I believe the PCs who didn't receive any Lightning Damage from the Stele had the medallions. A quick check might reveal the current owners.)

(I think the cards Teleportation Circle and Dancing Sword support the concept. Besides you can see Marlyth using a Torch (Delver's Torch), not an artifact but I found it interesting. @WILE_E_COYOTE)

Tabaqui nods to Calner, "Absolutely.  Plus, now I'm just pissed off at this lady-wizard and her minions.  We might want to consider another long rest before we head to this 'island' of hers, though.  Just to be at full strength."

Marlyth studies the texts of the Book and she realizes that the Wizard Leader Sylvene has possibly built a demi-plane by using a magic stone which is guarded by four guardians, there's a hound named 'Coriander' somewhere near a fireplace, she has been attempting to keep the 'Potato Stew' recipe secret by making trapped corridors. Besides, since the Planar Key has only one charge remaining, there's been someone else who might have used the key before the party discovered it, probably it was the hairless handsome wizard 'Malivar'.

"Let's take a short rest instead of a long one, Tabaqui. It will allow me to heal wounds and brew a drink from Theki Root."
