Quote from Wysperra >>

 Since Mage Hand is a cantrip I can repeatedly cast it. I give everybody -player and DM- freedom to use it. I can’t be on 24/7 and I don’t want the party slowed down waiting to poke something.

 

I utter more mystical phrases and use the Mage Hand the press each color combination pausing a little after each combo to see any results. “Is being like child’s game, except if lose, we die. HAH!” 

 

 Do you try every combination that Lumiere said?

Your mage hand tries various combinations and for some time nothing happens. This until you press the stones in the following order: yellow, blue, orange. When you do so the mist in front of you disappears leaving sight to a long corridor that continues in the dark.

Falmo will search for danger in the passageway: 16 or 17.

Do you enter it or just watch from outside?

Falmo is just watching.

You don't see nothing special in the corridor. It's made of plain rock and there are no more paintings on the walls. As far as your eyes can see it's a normal corridor.

Falmo will pick up a rock and toss it into the room.

The rock flies a couple of feets and then falls on the ground with a dry sound that echoes in the whole tomb. Nothing happens.

I light a two torches, casually toss one down the hall then take the other and give it a hard throw down the hall. Is anything new revealed?

"I believe we are all waiting on the same thing. Someone to go first." Lumiere says. "As this is staying the hand of the group, I volunteer to go first should you wish for me to approach first. Unfortunately I have no mystical communications should I end up not where intended, as in the other side of this archway, so make of that what you will."

"I'm fine with someone who's not me going in there."

Jerigg throws two torches into the corridor and they start illuminating the walls further ahead.

Nothing happens with the torches and you still can't see the end of the corridor even if the light reaches 30 feet ahead. 

"Let us pray that light guides the way." Lumiere says as she steps forward through the arch towards where the torches landed. She will keep an eye out for any more traps along the way.

Perception: 11
Investigation: 6

”What is this playing chickens? You cannot be sending leettle gurl by herself.” 

I move to stand next to Lumiere probing ahead with the butt of my spear.

I also cast detect magic

As soon as Lumiere and Jerigg stand into the corridor they disappear out of sight. One second before they were there, now they're gone. All of this in a blink of an eye. 

Falmo will backpedal quickly.  "That's why I let them go first."

Ubogri curses in Orcish. "Why can we see the torches, but not them?" He blinks. "Hello?!" he yells.

You shout but the corridor remains silent.
