The Valley of Ends

Onyx will look around for traps, before looking at the storries on the wall.

Gotch stays with the main group, but has his familiar continue to scout ahead with Onyx. (I am a bit lost as to where we are in relation to Onyx and Sabastian though. I thought Onyx was on the same level as us, while Sabastian was a level down.)

Looking around to find no traps or even the aftermaths of any found ones before looking at the gray images before Salys comes up with his glow ball bearings to show more vivid colors in the images. Closer looks Onyx finds the new images with two figures being worshipped, the slighty large one has the same hourglass symbol and he seems the second figure has it's arm up and faintly lines can be trace from it to the laying figures which are seen rising up. 

Onyx is on same level as the party. the level is just four rooms connected in a horseshoe design of hallways. Onyx is in the third room looking at the images on the wall. There are two large pitfalls between first and second room (which Sabastian went down) and another in the middle of the middle of the third room.

Following along with the group Resfaen is keeping a look out for anything hat might try to leap out at them.

Resfaen Perception: 7

AS everyone is looking around the area for hidden doors in the third room, a large explosion echoes through the sandstone tomb before something grinding noise followed as the floor starts to tilt and continues to tilt until the floor becomes a wall.

Everyone give me acrboatic check to keep your balance: DC 12 or take 2 as you lose your footing and fall onto the new floor, formerly walls of the 4th room. Those who make their saves manage to keep their foot and slid down to the 'walls' of the third room.

Sabastion was hit by the wall rather violently and is knocked back to feywild. 

Gotch dex save: 9

Dex save: 15

I assume the whole structure tilted, which rooms are up now and which ones are down.

Dex save: 19

The floor and ceiling just became walls, the walls just became floor and ceiling Room 1 and 4 would be lower levels now. The old floor and ceiling only leaves about 10ft space. 

Simple idea of the level: (Red is the floor now)

Salys dex save: 11

Bearskr dex save: 9

Resfaen Dex Save: 14

 "Argh, by the god, who touched something?" Resfaen screams out as she slides down the wall/floor, looking confused.

Onyx , Fingolin and Resfaen take a moment to look around at the new layout of the tomb before peering down what used to be a hallway and is now a hole where Gotch and Salys with his streel defender lay, bruised their ego more than thei backside for the moment. everyone could swear they didn't touch thing before the tomb seem to turn on it's side. 

Salys sighs and brushes himself off, spraying a fine mist over Bearskr to repair the minor damage and looking around the place, staying out of his saddle for now, "Perhaps its a simple counter weight? We put too much weight on this side and it tipped? Do any of you see anything?"

Mending

Investigation: 16

As soon as the mending spell finds repairs the minor damage to Bearskr, the rumbling begins again as everyone is slide the short distance to the original ceiling.  The floor is now the ceiling, the ceiling is the floor. The walls are back to be walls.

"Ok, it is a magic-sensative trap, if I am guessing correctly." Gotch says with a glance around. "Shall I cast a spell and see if it sets it off again?"

Salys, as curious as ever, promptly casts mending again, just to see what happens. 

„Try it. But i wonder what triggered the first shift?“ Onyx goes and checks the rooms with the pitfalls, if anything fall down now that it is upside down.

The ground tilts once more at Salys' sudden casting. Acrobatic check to keep your balance DC 12or take 3 bludgeoning damage as the party slides towards room 3's walls now. Onyx after recovering from the more sudden turn of the room as they were waiting for Gotch before Salys jumped the line, climbs up to the hole in the 3rd room, now a tunnel, and looks down to see nothing really, just more sandstone. 

The bones that Onyx uncovered, just the one Onyx opened, are sliding around as well. 

Acrobatics: 9

can Onyx reach the hole that lead to the other level? It should be on one of the walls now if i am correct.

“Those explosions may be someone fighting...“

Acrobatics: 19

"This is fun. It's a bit strange for a trap, not very effective. Could it be a puzzle? Maybe getting the rooms in a certain position reveals a new passage."
