Chuckling, Maximus smacks his forehead. "Well where is the fun in that, it is occasionally exhilarating to wake up in the middle of a rest with spiders chomping on your toes. Fine, fine if you want to be smart about it, by all means use the doorknob."

Long Rest

You enter the HQ and have an uneventful long rest.

Anything anyone wants to do extra during this LR, or are we ready to move into the next morning?

Pretty sure Maximus is ready to move on.

(OOC did Shadowlight return because that will determine what I do for spells in the morning, otherwise ready to progress)

Nothing for Stigr other than check in with the staff to see how things were going.

Before crashing out for the night, Rurik would check in to see how the modifications are going with the smithy. He would also get as much of a report as possible from Shadowlight and relay it to the team.

Rurik

Shadowlight lets you know the Southern passage you sent him down lead to a dwarf-crafted door. he was unable to get past that door, so was unable to go further than it.

All

Do you want to head South, to the door Shadowlight found, or continue East and check out the tunnels filled with webs?

“I’d like to see this door.” Rurik says simply after letting the party know about it. “I’m not quite in the mood for spiders, or anything else in those webs just yet this morning. I’ll go with the majority of course. No need to break the party up.”

"Way to the door works for me as well." Maximus states, updating his map with notes about webs and possible spiders.

Stigr shrugs, "I'll go along with wherever you all go."

Traveling South

Turning away from the Eastern passage you instead go South. After a couple hours of travel you come to the door Shadowlight found the previous evening. First though you notice...
In the middle of the hallway, crushed beneath a 4-foot-square block of stone that has fallen from the ceiling, is a goblin. Only its gangly legs are visible. (The goblin stepped on a pressure plate that caused the block to fall, and the trap no longer poses any danger. The goblin is quite dead)

Past the goblin is the door in question...
This thick stone door is flanked by bas-relief carvings of dwarves, their faces and beards chipped away. A dwarf can open the door, but no other creatures can do so except by using a knock spell or similar magic. The door has AC 15, 75 hit points, and immunity to all damage except force damage and damage dealt by adamantine weapons.

Seeing the goblin’s feet, Rurik continues to check the area as he moves towards the door.

“When you’re ready, I’ll attempt to open the door.”

Stigr shrugs, "If you can open it, great, otherwise I can try blasting it open, but it'll take some time."

Maximus goes and looks over what is left of the goblin. "Not a way to go but at least it would have been quick."

Perception: 7

“Haha, a way to go indeed.” And Rurik turns back to the door chuckling to himself.

Hall of Stone

Rurik is able to open the door easily. The door opens up onto a large chamber...

Big Xorn. An unusually large xorn, 10 feet tall and 10 feet wide, sleeps soundly in the middle of the room. While asleep, the creature remains standing, its mouth and eyes closed, its arms hanging limply with knuckles scraping the floor.
Stone Cubes. Twenty cubes of solid granite measuring 8 feet on a side are arranged about the chamber.

Maximus whispers to the group, "Let's not try and wake that thing and move through this room as silently as we can."

“Or we leave it be and close the door back up, and sell its location,” Rurik whispers. “But if you really want to, we can try.”

Chamber

Rurik would easily notice a door on the far side of the chamber, one that looks very much like the one you opened up on your side of the chamber.
If you choose to go across the chamber I will need stealth rolls from everyone.
