GB will cast a Fire Bolt at the wall next to the doorway as a warning.

"Show self noisy thing!"

The sound keeps getting louder, shuffling and scraping, with the occasional moan, but nothing comes through the door. 

Spirit looks at the door curiously, as if wanting to go investigate.

"GB follow cat."

He stats as he slowly walks to the door gesturing for Spirit to check it out further.

GB, as you draw nearer the door, you can make an Intelligence (Investigation) check.

Investigation 7

Peering into the dimly lit courtyard outside the room you’re in, you can’t see anything at all, but the noise of alternating scraping and shuffling sounds almost right on top of you!

A few seconds pass, and then, without warning, the sound abruptly stops, giving way to dead silence, save for the gentle roar of the flames coming from your torches.

No enemies appear, and Lana’s bow is also giving no warning any longer.

Idalla still looks terrified.

GB turns to the party and shrugs,

"Probably nothing. GB see nothing"

Idalla replies, hesitantly, "It...it has to be the wizard. He enjoys toying with the minds of others. But he is still very powerful. He could summon monsters in an instant. He once threatened to have them tear me limb from limb if I ever thought of escaping...I thought that was it! Please, please, you have to kill him! You will have to be silent and swift to sneak up on him, and I know just where to go! He hasn't been careful to hide it from me."

She describes to you a secret passage adjacent to her holding room. "It is on the wall just to the left of this room, as you exit. Look for it, and you will find it. The passage takes you into the old dwarf quarters, but also to the wizard's dwelling, one level down. But do not descend too far, for remember, the ancient black dragon lairs at the furthest depths." 

“I would guess he already knows we are here. Let me investigate the passage first.” Bel moves to the secret passage doing his best to stay hidden

Stealth 18

Lana follows with Spirit quietly and quickly

It is easy enough to find the passage, just a few strides from Idalla’s prison. The telling feature is like the old secret doors you had found days ago at the Mountain Door, the ones that led to the archer posts. But this one opens into a disused passage with no lighting. Besides dust and thin cobwebs, nothing else seems to be here. The passage is a straight run towards an opening that you can feel from the change in air pressure, but seems to be just on the edge of your vision. The sound of rushing water can be heard. 

On your right, just 30 feet or so down the secret hallway, is the passage Idalla spoke of (which presumably connects to the back end of the dwarf forge and quarters).

Idalla, meanwhile, beseeches you on last time. “Would one of you stay here to protect me? Now that my door is breached, it’s not safe. I can’t leave, but neither can I protect myself. There are...other dangers here besides the wizard. Besides the insane dwarf ghost, there are undead orcs and dwarves that occasionally roam the halls. They have never been able to penetrate the entry here before, but now that it is open, I fear the worst. Perhaps...you, my good sir? You seem strong and able, but perhaps not the sneakiest?” She says, addressing Aregarak. “Would you stay with me? Please? I promise you, the reward for my rescue will be more than worth it.”

"Perhaps it is you who should come with us, you will be safer that way.  If this wizard is as dangerous as you say, my friends here will need everyones help to defeat them." and he'll heft his greatsword up to his shoulders and flex his big rippling muscles a bit in an impressive display of physique.

“You are...very impressive, great hero,” says Idalla, obviously taken with Aregarak’s great stature and physique, “but remember, the wizard has cursed me. If I leave this room, I will simply begin to die a painful death. The wizard must be defeated, and I fear for my safety if I am left alone. Please stay with me!”

// Let me know how you are proceeding! //

//Bel is ready to go. Anyone else going to follow?//

Aregarak is in a quandry, he looks at Idalla and then looks at Bel, GB, Lana and Spirit, then back to Idalla you can see his brow furrow as he considers the options.

He will then attempt to pick Idalla up [Grapple: 25]....and then carry her out the secret doorway over his shoulder....

As you begin to carry Idalla towards the door, she struggles and protests, “Put me down this INSTANT!” she commands in an authoritative tone. But as you draw nearner the exit, her demands subside into pleading, begging. “Please, you will kill me! Do not do this!”

GB suggest to Aregarak,

"GB thinks we should leave her."

GB then to the lady in his arms

"Lady, you have survived here longer.  GB need big guys strength.  You carry on, GB and us carry on, we join when beastly dead.  Good?  Good."

Idalla looks exceptionally panicked at the moment.

The minotaur contemplates everything and it makes his head hurt.

He sets Idalla down and grabs one of his javelins and goes back to the door they originally came through and closes it.

Then he takes his javelin and jams it in between the door and the frame to effectively prohibit it from opening.

[STR check: 26]

Then comes back to the rest of them and says "That will hold the door, this will save your life...." and he hands her one of his handaxes. "Anyone not us hit them with the sharp end..."
