"And I was expecting a challenge. Hah!" Gothazar joins Leif on the platform.

 Almost on cue with Gothazar's claim, the tree fills with the sound of splintering wood, and crumbling rock. Leif and Gothazar's ladder runs break, and the violent shaking if the tree send Asgrim and Eidren tumbling down the ladder chute.

 Gothazar is able to grab onto the next ladder run, and catch Asgrim from the air.

Leif and Eidren fall, landing on the head of the Elven statue, taking 2 damage (already subtracted).

In the split second you have, you see The entire cavern is crumbling, and the tree is collapsing. You don't have much time!

Asgirm takes hold of the ladder and puts his foot on a rung with a series of curses even though he's thankful for Gothazar's help; looking down at his tow fallen companions. After another series of curses, "You two okay down there?"

Gothazar looks around for a way down and to see if the tree seems to be continuing to collapse

Perception 15

Eidren picks himself up and hops down to the platform below.

“I’m ok” he yells up to the others while he help Loef to his feet. 

“My back is a different story” he mutters. 

He looks around to see if he can secure an escape before the entire place collapses on them. 

Gothazar sees the tree is splintering, it won't be long before the entire tree comes down. Eidren sees the bridge is also going to collapse.

Eidren grabs Leif and shoved him across the bridge. They sprint for the exit. 

Gothazar will cast Bless on himself and asgrim before jumping down to follow the other two

With another string of curses, he lets go of the ladder, dropping down and follows the rest.

pieces of the walkway star to collapse, and high pieces of the stone ceiling start to fall.

As they make it to the exit, the floor starts to fall beneath them. They jump, and hold into the ledge. Leif and Eidren grab them, and pull them up. You all take a minute to breath. While you look around, you see a pile of stone, dirt, and tree bark where the mighty tree used to stand.

"That is some shady construction right there. The owner of that tree should hire a better mason next time he plans on making another house."

Leif lightens the mood after their daring escape from the current pile of ruins in front of them.

"Let's move forward to our next destination, the cave just outside the village called Maw of Njörðr."

"I agree we should move on, but let's take a moment to rest, my friend," Asgrim says, his wide. He's been in many battles before, faced down legions iron-clad foreigners with his teeth bared but having been nearly crushed by a giant tree had shaken him, the adrenaline coursing through his body is enough to leave his hands shaking, and although he's very used to the feeling, there's just something wrong about dying underneath tons of rubble. But, he wasn't going to show that to the others; he's keeping a brave face, a savage grin despite the near death. "I could use it, and I think so could the others."

Leif looks at the bruises he had during their skirmish with the bears and his last failed attempt to land with Eidren.

"Then how about we take an hour of rest before we proceed to our next destination?"

"My friends speak wisdom" Gothazar looks around for the remains of bears from earlier and begins to butcher them for a ''mid adventure snack"

“Whatever you need.”

Eidren ignores his companions during the rest. He pulls out the crystal and studies it, turning it over and over in his hands. 

As he is cooking Gothazar will keep an eye on Eidren and try and draw him into a conversation in an attempt to see if this obsession will become a problem with their mission.

Insight 10

Spoilers: it might be. 

Eidren is too distracted to be deceptive.

Gothazar doesn't see anything about what Eidren will do, you can just tell that he is very intrigued by the item.
