Tyris nods back to Oreus, then waits for Shadows answer.

"There are children and it looks like a buyer is here.  We need to go quickly.  "  shadow attempts to open the double doors

The doors should open into the chamber beyond, but they don't open. They appear to be locked or perhaps blocked. 

"We might have to find another way. Let's go see where those last 2 hobgoblins came from.  " shadow will head to the east side far door that the last 2 seemed to come from

Shadow will check the north and south rooms on his way to the open east door, don't want to leave enemies behind us

Shadow moves towards the opened doorway to the east, as he enters the eastern hallway he hears the sounds of a roaring fire and hammers striking metal. Looking through the opened door to the north, Shadow sees a big room that is obviously a barracks. These barraxk,which hold four rows of iron-wrought bunk beds, csn accommodate 32 guards, although it looks like only half of them are being used. Currently the room is empty. 

Do you still want to open the southern door, or proceed towards the noise to the east?

Open door to south

Shadow opens the door across the hall from the barracks. He sees...

An iron cage dangles from the ceiling in one corner of this rectangular chamber. Trapped inside are two enormous beetles that shed a hellish light. The room’s furnishings include a large bed covered with animal hides, its corner posts shaped like dwarven sentinels. Next to the bed sits an iron trunk with claw-shaped feet and four chains bolted to its sides.

Shadow will inspect the trunk 12

As Shadow moves into the room to check out the trunk, two unnoticed blobs of flesh materialize into hellish creatures and move to attack Shadow. 

L1 Fist Attack: 15 Damage: 3. The first creature's attack caught Shadow by surprise, and the fist struck home.

L1 Fist Attack: 7 Damage: 2, the creature misses Shadow. 

Everyone roll initiatives.

Lemure initiatives 0

Fario's initiative 17

Fellian's initiative 5

Alben's initiative 3

And as no one has a negative initiative, you all act before they do, (you don't even need to roll if you don't want to.)

Oreus is disgusted by the sight, luckily he can attack one from outside the room: he does that and then retreats a little backwards to let the others contribute

SINCE I HAVE WEAPON WITH REACH PROPERTY:

Attack: 14 Damage: 8

bonus Attack: 20 Damage: 7

re-rolling the second damage because of great weapon style: 7

Oreus is able to kill one of the creatures (I'm going to assume L2 unless you say otherwise) with his reach weapon. Clearing the way for the rest of the party to move into the room. He then backs away from the door. 

Tyris moves to get a view into the room where he can see the new foes, then marks it and launches an arrow.

(I think the space just north of Alben should have LoS on L1, and any cover from doorway shouldn't matter with Sharpshooter)

Attack: 21 Damage: 8 + 5

Tyris is able to kill the 2nd hellish creature with a well placed arrow. 

Everyone receives a whole 2 xp.

Shadow if you still want to explain the trunk, give me another investigation check. 

Does anyone else want to do anything in these two rooms?

Investigate 7

The four chains that are bolted to the trunks side are about 3 feet long and end in shackles. The trunk itself is locked.
