Once Brandor has either caught himself or fallen down (i.e. Staying out of the way so as not to have a dwarf land on him!) Grum will also begin to climb.

Athletics: 23 plus 3 guidance.

(Not quite sure which way we're going, but Grum is going too! This is climbing up the rubble mound to get to the small side passage? Or was Brandor trying to climb the rock face to get straight up to the bridge itself?) 

 (My understanding is a rubble slant followed by a roughly shear wall.)

Unfortunately the rocks could not bear the weight of the Dwarf and the rocks begin to slide down. Brandor manages to swiftly step out of the way and prevent any more from falling and he doesn't fall down with the rocks but it made quite some noise. He finishes climbing up and Grum joins soon after, the loose rubble now clear and fallen enough that there is a clear path upwards now. There is a hallway to your left at the top and another to your right with the bridge behind connecting to another passageway that seems to be leading to the waterfall. You hear some unintelligible goblin chatter towards the left.

(unintelligible because it's too far away? Or can Grum understand any of it?) 

Initially you can only hear mumbles, but you can make a Perception check to maybe make out the words

Perception: 24 

<Squelch> follows the party.

Acrobatics: 19

Perception: 8 to hear the goblins. (OOC he doesn't speak it, just for mocking them later)

You hear a few voices, you can make out three at the moment:
"You hear something?"
"I hear that noise."
"What noise? I only hear waterfall."
"Gurp, you go look."
"Fine."

Grum will whisper quickly to whoever has followed (possibly the whole party now the pathway was clear?), "They heard the rockfall. Someone's coming!"

Grum will quietly draw his bow, huddle up against the wall to try and hide, and ready an arrow in case a goblin comes around the corner. 

Stealth: 24 

Alright, everyone roll stealth checks as you head up the passage

<Squelch> imitates Grum's strategy. He crouches close to wall and loads his crossbow. If he has a clear shot, he fires.

Stealth: 18

Attack: 13, Damage: 10

Callie readies her shortbow and presses herself against the wall, trying not to be seen.

Stealth: 12

Brandor starts to lurk down the passage and readies to charge the first goblin that comes around the corner.

Stealth: 12

If/when the goblin comes into view, Grum will fire his arrow.

Attack: 12 Damage: 8 

The goblin makes it way down the bend,
Perception : 5
It comes around the corner and doesn't spot any of you, but it comes all the way down to the bridge nearing the other goblin corpse but doesn't seem to see it yet. As it becomes visible and you were all readying actions you all have one surprise round on the goblin as Squelch's arrow just misses the top of its head

The dwarf practically pounces on the goblin coming down the hall. He takes care to sweep around the back of the creature in case any of his comrades manages to take a shot with a bow. The goblin could prove to be excellent cover from friendly fire!

Staff: Attack: 6 Damage: 8

Stealth adv: Attack: 18 Damage: 9

Punch: Attack: 25 Damage: 10

Stealth adv: Attack: 15 Damage: 4

After noticing Squelch’s attack, it turns around just in time to see Grum’s arrow and dodges it, but the Hill Dwarf springs into action, coming down with his staff onto the goblins skull and spinning on his feet, driving the momentum of his fist into the goblin’s face as you hear a *crack* and feel it’s jaw dislodge and splinter on the inside, and it falls next to the other one, dead. 

Grum comes quickly and quietly to join Brandor.  "Let's get these bodies away from the bridge."  As he says it, he picks up the goblin that was shot earlier and carries it 20ft back down the passageway.  Then he'll go back up to where Brandor killed the goblin and see if he can see how many goblins there were to the left where the voices were coming from.

Perception: 9

(Would I need to roll a new stealth check having fired a bow, or would the previous one still stand?)

<Squelch> searches the goblins for anything interesting and helps hide the bodies while quietly muttering funeral incantations.

Investigation: 2

He then reloads his crossbow, points towards the passage with the other two, and shrugs.

If needed, Stealth: 7, Perception: 5

(Previous stealth rolls still good since it was a complete surprise round against the goblin)

About 40ft from where the dead goblins lay, the western passage leads around two bends to a large cave divided by a ten-foot high ridge. A steep natural staircase leads from the lower portion to the upper ledge. The air is hazy with the smoke of a cooking fire, and pungent from the smell of poorly cured hides and unwashed goblins. You can see four goblins in this chamber, tending to the cooking fire in the northern part of the cave. Up at the top of the stairs, pressed up against the wall you also see a human male chained up to a post and he seems to be unconscious right now.
