Crimson Sands of Time

Angus Athletics (if the others want to try this way) 23

Athletics 20

(DM do you want me to add the hole into Sam’s inventory, or do you want me to remind you about it later?) 

You can inventory portable hole.

I think ddb uses it as storage position, which could be handy for magic items.

Angus and Sam pull their levers with little difficulty.  Is Tetrevess pulling as well?

Yes, Tetrevess attempts to pull his as well.. 9 athletics. 

Tetrevess takes longer to pull the lever down and is exposed to Far Realm energy. It takes 13 psychic damage and gains 1 level of exhaustion as he receives a vision of the past.

From the darkness, a vision emerges. A dragonborn artificer can be seen in the spire of a tower, gathering purple crystals filled with the power of the Far Realm.

Outside the tower, gargantuan tentacles covered in eyes writhe up, destroying everything they touch. Worms and unspeakable aberrations cause carnage in the city below, before an even larger tentacle, nearly a third the size of the city, emerges from a portal and slams itself into the dragonborn’s location.

The large green crystal embedded in the thick stone door on the south wall, by the stairs at the entrance lights up before the door slowly sinks to the ground, revealing another room. It is clear that all the artifacts stored here have been looted. Telltale gaps in the dust and sections of unfaded paint show where large objects have been removed. The only thing left behind is an ancient scroll lying on the ground next to a shattered scroll case.

Sam won’t move to pick up straight away but will investigate 

13

Tetrevess staggers from the onslaught of psychic energy, and then relays the vision to the group.

Sam looks at the scroll and he can see its a drawing if somw type of device, but can't discern its purpose or function.

(Are there more exits/rooms or does that complete this area?)

Pain.

Spoiler 

Seeing San srruggke witg the scroll, Tetrevess looks ut over abd realizes it’s a schematic of “the Anomaly,” a device designed to safely drain large quantities of Far Realm batteries of their energy and to completely sever their connection to the Far Realm so they could never be recharged.

<This is exactly what you are looking for, but, sadly, the Anomaly was taken by the neogi and must be located in a future adventure (DDAL￾DRW-EP-04 Tears among the Stars). Not necessarily. Reviews are not kind.  I don't really plan on revisiting this, but as you've likely guessed, you don't really need that macguffin>.

While Sam and Tetrevess inspect the scroll, Angus finds a 5-foot-wide section of the southeastern wall is illusory.

As he passes a hand through the wall, he is atta jed by rwo cultists from within the room behind the illusory wall.

Roll for initiative 

17 for 4 slashing

14 for 4 slashing and 8 force damage

Shoukd you see past the illusory wall, you will find the next room (where the cultists were waiting) is 10 feet long, 15 feet wide and in complete darkness. 

< I'm not totally clear on whether lights like torches and flaming daggers illuminate theough rhe illusory wall, but I am inclined to say no.  If you enter that room, lights ablaze, then the room is brightly lit.

And yes, I know 'blindsight', but unless I heard Angus say 'I check the walls' or something, to say he's within 10 feet of that spot, it shouldn't be automatic.>

Meant to say they are wearing black robes and one has an unusual looking gauntlet on one hand: Jade-like stones carved to resemble dragon scales cover the back of this mithral gauntlet. 

Initiative 17

(Have the cultists entered the lit room?  Did they pull Angus through?  trying to figure out which room I'm in and how many enemies are in reach)

<It's Angus' arm, you decide.  If you walk through the wall, it's in there. If you just put your hand through or you look like you're about to, they jump through and attack you in there.  PCs would be surprised, but I don't really care, so just act on this turn.  For Angus, it matters less than most since the presence or absence of light is pretty moot. RAW it's funny b/c the lack of AD / DA tells us nothing about whether you and the cultists can see each other.  These guys have 9 hp.  It hardly seems like a thing worth worrying about.>
