Misha directs the others to move back30ft down the tunnel as he casts his spell and then he starts moving back too once the range comes within 30ft.

Target follows the directive moving back while shoving the torch and tinderbox back into his pack.

Misha works with the bonfire to create a safe path through the fungi

Rashana backs away as smoke and steam fills the room, sniffing the air speculatively. When it eventually clears she looks at Misha, waiting for him to continue.

"Lets wait a few moments for the air to clear and then continue" 

As they wait he pears towards the other side, and listens, attempting to ascertain, if they attracted attention with the light show he just put on. Then checks behind them.

Once he's sure the way is clear he proceeds.

Seeing that the way is now clear, Misha leads the way to the other side.

The group comes out to a large cavern. Glittering minerals in the ceiling of this large cavern catch the light and send it back to create the impression of a starry night sky. Dozens of skeletons—many crushed under fallen debris—are scattered across the floor.

Saravena headed towards the nearest structure.

Target follows, axes in hand.

Misha joins Tagret and Saravena 

...and Rashana follows Misha once more, assuming none of the others die of smoke inhalation in the mean time.

Saravena senses a subtle aura of magic in the cavern as she approaches the structure. It seems to be stronger when drawing closer to the northern building.

Gundren admires the minerals in the ceiling, "I'm not sure what they are. I don't think they are valuable but they are pretty."

Rashana nods at the escarpment, "Upon lofty heights, the nature of the domain, may become more clear."

"Gundren, what did they mine here anyway?" Misha asked, looking at the scorched buildings.

Grinning to herself Saravena closed on the Northern building.

Investigation: 9

"I'm not sure," Gundren replies still staring at the roof of the cave. "The tales failed to pass down the specifics. However, there should be a temple of Dumathoin somewhere around here. That would lead me to believe that it was gemstones of some kind or another."

He then turns his attention to the two structures. He looks between the two buildings comparing them to each other. He then begins wagging his right index finger in excitement.

"Wait a minute, wait a minute, I think these are the Wizard's Quarters and the Forge of Spells. We should find the answers to all of our questions here. Possibly the majority of the remaining treasure too. We should check them out whilst we're here."

“Treasure? We’ll lead the way.” Target says with a big grin on his face.

Rashana was moving toward the escarpment to get a better view of the entire cavern, but seeing everyone heading to a specific building, she follows.

Misha moves with the others  he looks for dangers and other things.

4 perception.

Gundren leads the way to the structure that he identifies to Wizard's Quarters. The group comes face to face with double cracked doors, the hinges of the doors are partially melted. The condition of the doors means they won't open.

"I think we're going to have to break those doors down," Sildar says.
