I open the silver chest.

Aera follows Lirin in the secret door. "Good find!"

Quote from Kaldaras >>

"You want to resht? We are barely here for an hour!"

Lirin is anoyed and starts to investigate the chamber to look for any more hidden traps or secret doors. Investigation 20.

After he is done with the room he extends his search a few feet into all ecits to the room. How many are there by the way?

 
Klong agrees with Lirin. "Klong not here for nap! Klong here for adventure!"

Klong follows Lirin and continues to look in the tomb.

Inside the chest is a small silver box.

Also I can’t tel, has anyone looks around the corner yet? 

Of the trapdoor in the room with the chests?

Of the secret door’s hallway 

How wide is the hallway? Also I assume it's been more than 10 minutes so my darkvision gift to everyone has faded. 

About five to ten feet wide.

I'll tap Lirin and say, let me take a peek to see where it goes next. I'll poke my head (only) around and look to see what's around the corner. 

I take the box and open it.

When you open the box, a trap is revealed. Eight darts fire at you.

Dart 1  Attack: 28 Damage: 6

Dart 2 Attack: 14 Damage: 1

Dart 3 21 1

Dart 4 Attack: 28 Damage: 5

Dart 5 Attack: 18 Damage: 5

Dart 6  Attack: 18 Damage: 6

Dart 7 Attack: 26 Damage: 2

Dart 8 Attack: 24 Damage: 1

 Sorry about dart three, it somehow got 8 when rolling a D6 so I just rolled using my IRL dice.

 Lirin moves over a bit to let Aera pass and have a hlimps around the corner. Wordlessly, he reaches into his backpack retrieving a small silver mirror after a few seconds of rummaging and offers it to her.

Before, she sticks her head out, she turns "oh thanks". then uses the mirror to look down the hallway.

I take all 8 darts for 32 damage... I then move over to the wood chest and open it.

Down the hallway is another hallway, but wider, you can’t see the end but the area you can see has a piller next to the other wall. with a yellow orb floating above it.

 Inside the box is a ring of protection.

Aera can see as far as the hall is long. She has no maximum limit to her dark vision. 

How far down is the pillar and the orb?

The pillar is about five feet tall, with the orb floating three feet above that.

How far away is it?

I put on the ring of protection.
