Hifu says to Gilgin, "It is a warhammer from my maester that taught me about martial arts and fighting, he died from his injuries protecting Lonelywood, but I never knew it was magical!  I wonder what it does..."

James lets out a groan as Gilgin wakes him.

"Aahhh...what...where am I?"

James looks up, eyes blurry, looking back and forth, trying to remember.

"oh right, we're still out in this gods forsaken place."

James slowly gets to his feet, still looking very exhausted.

"Right, just point me in the direction we are going, I'll be ok."

James doesn't look ok and is still moving sluggishly.

All three doors look like plain marble slabs. The one that connects the outside and the inner part of the tomb is smooth on both sides. The one that lead to the druids hideout, had the crystal on the inside and the last one (S) is smooth on the outside, but you don‘t know how the inside looks like.

Gilgin, what you do know: there are several ways how such a glowing effect could be triggered. It could be a command word, it could be the presence of a certain creature, it could be because the wielder fulfills a certain criteria like race or character alignment, it could be because the weapon choose to bond with the wielder or that the wielder attuned to the weapon. You do know that concentrating and meditating (attune) while holding such a weapon usually reveals most of it‘s properties. Such an approach will not reveal curses or warded properties, for those you will need  magic to identify them.

Nyx looks at James and visibly deflates. "Ok, we're not going to make it back to the town today unless we carry him. And I don't think we can carry both him and the huge head of the moose at the same time."

She looks around the room some more. "We need to make this a safe place to rest. Lets see if the outside door or slab can be closed and re-opened. Then gather some firewood and lets roast some of that moose. We can also bring in a bunch of branches of the evergreen trees growing nearby and make ourselves proper bedding."

Nyx continues, "Gilgin, you know stonework and Kravek you are strong. Can you two figure out the outside door please? Hifu, lets go gather some firewood. James, do you know how to skin an animal? Either way, can you remove the skin from one side of it? Dinner is roast moose with a side of ... we'll see."

Hifu likes the plan and gives Nyx a thumbs up sign.  "Right, I'm on it."  He steps outside, looking for any sign of the druid, then begins to search for firewood for the fire.  

Perception :  15

After that is done and he is inside again, he plans to sit down and concentrate / attune to the Warhammer to figure out more (if he can) about it and what it does.

Hifu, you don‘t find any hints of the druid, but you do find plenty of dead wood. You also do notice that the trees inside the barrier are healthier and with less damage from the frost.  

Gilgin chortles, “I look forward to a good bit of moose!” Before inspecting the stone door, trying his best to see how he could get it open after closing it.

Based on all the moon symbols around and the ones that are glowing, you come to the conclusion that the doors must be somehow connected  to the moon dial outside and that the right moon phase will unlock the corespondent door. You‘re still confused what the silver plated full moon over the mirror was for and how the druid triggered the half moon to get into his chamber.

Gilgin, you think the crystal that was removed has something to do with how to open it from the inside, but it is broken now. You may be able to mend it, if anyone knows that cantrip...

As for the other two doors, the only way you can see, is to wait until the right phase. But looking at the collapsed wall, that opened and gave entry to the tomb, there may be another more permanent solution on how to open them.

“Alrighty Nyx, I’m gonna need that stone...” taking the stone he puts it up to where it broke off from and casts mending, trying closing himself in and attempting to open it after while leaving everyone else outside

Hifu says "I have an idea."  After seeing the opening to the tomb and thinking about it, he feels that another opening needs to be made.  He goes up to the easternmost / southern statue inside the structure and shoves it forward, northeast, trying to get it to crash through the northeastern wall.  

Nyx says, "Sure. You do you. I'll do cooking."

She'll build a fire just to the south of entrance (the broken wall), on the inside of the wall (assuming the room is pretty high). And she'll start prepping proper chunks of moose meat to be roasted. The fire won't be huge, just good enough for cooking and warming up the interior.

James nods understanding to Nyx' request and heads over to try and skin the moose, at least enough to get at the meat.

After Hifu bring the wood and Nyx builds the fire, James waits to assist the diminutive halfling with whatever she needs.

James watches Gilgin disappear around the bend to the druid room, but is too tired to notice if he returns.

Gilgin, it takes you a few minutes and several castings of the spell to mend the crystal back to the door and repair the marble that got chipped away. While you do that, you notice that a part of your divine energy gets absorbed by the crystal and you hear a faint click from your door each time that happens. Once you are done, you test your theory, you lock yourself inside, count to three and channel some magic into the crystal...you hear the click again, the door unlocks and swings open a little bit, enough to grip it and pull open. 

when you leave the room to report your success to the others, you notice that the halfmoon above the outside of the chamber stoped glowing.

 Nyx, you get a fire going and you find some nice big stones near the collapsed entrance, to arrange around the fire, to use to cook. James, you are to tiered to do a god job. It takes time and you make a bloody mess out of one of the legs of the moose. From a butchers or chefs point of view, the quality of the cuts isn‘t great, but it is meat and there is plenty of it.

Hifu, the statue doesn‘t move, so you call Kravek over to give you a hand (16) and together you are able to topple the statue from its pedestal. It hits the wall and the statue shatters into several pieces, but the wall itself only got a small dent, not even a hole or a crack. 

James gives Nyx a sheepish half smile as he shows her his "handy work".

"Ah, sorry, I kind of had some trouble, and then I tried to fix that and...well you can see it kind of went down hill from there."

James sits down against the wall, near the fire and before long he is struggling to keep his eye's open. His head occasionally dips down before he sits back upright with a start, only to repeat this again a minute later.

When Hifu and Kravek manage to topple one of the statues, James comes fully awake with a start, but even this is no match for his exhaustion, and he quickly settles back into his half asleep state.

Nyx nods at James. "You have done well. You can lay down, I'll let you know when food is done."

She turns to Hifu, "You found some very nice firewood, thank you. Just one last thing if you could - can you find some thicker branches of the evergreens outside and bring them in? Would create an insulating layer on the cold floor. We don't want James to get too cold, he's been through enough. Or ourselves for that matter. Take Kravek with you - he's already salivating, but the meat needs to cook a while longer."

Hifu acknowledges Nyx, "Alright, will do.  But first I need Kravek's help to topple this stone statue and make another opening in this wall.  I feel that we need to get the moonlight onto this southern door to be able to open it."  He asks Kravek for help to push it over, then gets the evergreens and additional branches to cover the floor as Nyx said.  

After he's resting and waiting for the food to cook he will continue to attune with the Warhammer.

Kravek will help Hifu to try and topple another one of the statues, hoping it creates more than a dent this time.

If they dont manage to topple it or if it does not do more than the previous statue Kravek will try to see if he can spot a weaker spot in the wall and use his warhammer to chop into it to see how well that goes. Perhaps we can make our own entrance with a little effort. He wont try it very long if it doesnt seem to be making much progress

Str check to push the statue (with adv from Hifu helping) 22 , thats right big man coming through

You topple another statue, but again, not much more then a dent. You get the feeling, that the marble slab that is the door, may be the weakest spot.

When Hifu and Kravek topple a second statue, James asks Nyx,

"What are those two doing out there?"

Nyx says, "I think they're trying to make more smoke holes, but the fires I make don't smoke that much. I know my stuff."

She cuts off a thin strip of meat that was hanging separately from a larger chunk and looks nice and crisp. She hands it to James, "See how that tastes"
