Again, nothing happens, but you get the feeling you're supposed to do the gesture for something.

Aeson:

Aeson casts Guidance on Raishan.

Raishan, see if that brazier can be lifted maybe?

Leshanna shrugs and moves to see where they can go from here.

She moves to check the small door to the south.

Perception: 18

Leshanna

"This door seems safe."  Leshanna tells the others.  "Shall we continue or do you have more you wish to do here?"

Reaching the end of the dark hallway Tarkin will remain in the shadows look into the room. 

He should see Aeson and Raishan standing near the brazier. They dont look like your typical cult he thinks.

Tarkin keeps watching a bit more, unsure that it is safe. Also seeing Leshanna inspect the south door. 

(perception to hear what they are saying 8)

He will assume these people are exploring the tomb since they would of know about the boulder trap if this was their own place. 

Before revealing himself he would like to know more about their intensions. So he will try to stay in the shadows and follow them from a distance, only moving out once they leave the room. 

(stealth to remain hidden 20 )

Raishan will inspect the brazier and see if there is anything special about it and then will go and inspect the rugs hanging on the walls.

Investigation brazier: 7

Perception Rugs: 10 or Investigation Rugs: 13

While investigating Raishan starts to comment, "I know we did the ritual right but I would have assumed something would have happened.  hmmmm, maybe since we did the ritual right nothing happened which is a good thing. I am not sure, once we are done investigating, should we just move on?

Raishan:

 Tarkin: 

We cannot afford to spring another trap, however I trust in the guiding light.... Let us move on.

(Assuming they went through the small door.)

This dark room has row after row of shelves. Desks lie strewn about the room, some on their sides. Cob webs cover every surface, and several large spiders crawl away at the sight of the adventurers. An unearthly female voice comes from the far side of the room. "Who are you! What do you want!"

"We seek to find an evil man who has recently entered this temple."  Leshanna calls out.  "Do you know where this man has gone?  We seek nothing else from here."

A flickering image of a human female approaches. "My name is Ilda, I am the keeper of Diderius's library. I know nothing of the man you seek." Suddenly the spirit screams loudly, then smiles at the group.

I will once more raise my hand as if holding a lantern and then turn my head down, whispering out "Mystra be praised."

"It's a library? We should probably leave. I don't know what good could possibly come of books. They aren't fine dining. They aren't meant to cushion your cot. I simply don't understand why people love books so much." Free Mistylance the posh Silver Dragonborn that you all definitely remember and who has definitely been here the whole time says.

"Mayhaps we should try the other door then."  Leshanna suggests, nodding back to the previous room.  "There were doors heading the other direction."

The ghost looks confused. "Books are good for everything, that is why I must protect them for my master. If you wish to see him, there is a door leading to his throne room, that way." She points to the North wall of the library. 

 Rest easy spirit. As my partner said, we wish no evil upon you, these books, or your master. What can you tell us about him? Would we find him agreeable to helping us?

"My m-a-a-a," The ghost suddenly starts crying, then laughing, then crying again. "My master has been helping you more than you think, but he is long dead."

(Edit: Can I get a perception check please.)
