Thror crouches down trying to hide in the foliage of the forest as the party decides what to do. Still eyeing Nix suspiciously he says a hushed voice, "Can we really trust the greenskin te not alert her friends te us? Or maybe she be leading us te a trap. I've never seen a goblin me can trust te not stab me in the back at the first chance."

Lorahzt longingly looks at the darkness of the cave, so close, yet so far... then her ear twitches as she listens to the others whisper among themselves. "I would have to agree with the dwarf, this one and her friends ambushed us and our employer before us. If we must go inside, let us trust only the word of one of our own."

Lia looks Nix in the eye and says “Answer the half orc truthfully or he will kill you. What will we find inside, and where do we find our friend?”.

She will listen to what Nix says, and then tie the goblin to a tree, before taking out her short bow and saying to Cade, “Yes, I’ll cover you if you want to take a closer look”.

Lia keeps watch for Cade and hides as best she can using her Mask of the Wild racial trait:

Perception: 20 

Stealth to hide: 11 

Ologu will probe with questions regarding occupants, rooms, traps, and most likely location of their prisoner. He will be looking for signs of dishonesty. Afterwards, he will re-gag Nix and help Lia tie Nix to the tree, being none too gentle with the constriction of the rope.

Arame goes up to the goblin Nix and asks,   where is the castle the Dwarf was taken to.?

This cave here is your hideout, what can we expect to find there? What does your lot usually do with prisoners?

She looks at Thror and Lia and says, we need to find out where they took Gundren.  

In the meantime, Arame begins casting Find Familiar as a ritual. 

 If you guys can give me 10 minutes, I can send my owl in to the cave first.

"Aye. That we do. It wouldn't do for that ol' Rockseeker te kick the bucket and taking me debt with him te the grave. Especially not when me's being so close te repaying it!" Thror responds in agreement to Arame, "Go on than lass, do what you need te do before we storm the place."

With the current plan(s) of action established, Lorahzt nods once and helps Lia keep watch. Even half-blinded by the sun, two pairs of eyes are better than one, she thinks.

Arame really hopes the goblin answers her questions regarding where the castle is that Gundren has been taken to. She doesn't like the sound of a giant spider either.

After ten minutes passes, Arame sends her owl to scout ahead inside the cave.  She sits under a tree while she is deaf and blind to everything but what her owl, Sally, sees.

While your familiar is within 100 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your familiar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the familiar has. During this time, you are deaf and blind with regard to your own senses.   

(Doesn't find familiar take 1 hour to cast as a ritual?)

Cade moves quietly towards the cave...

Perception: 7

Stealth:  20

Ologu, Nix refuses to answer any more questions. You get the feeling that she might just betray you if you don't act quick.

Arame, for simplicity, let's say you were able to cast find familiar before the goblin ambush. Your owl flies into the cave, and notices the occasional footsteps of a goblin, as well as huffs and snarls coming from somewhere just inside the cave.

Cade begins to scout ahead and Lia and Lorahzt watch out for him. Cade, as you crosses the stream, two goblins who are taking watch in the thicket across the stream take notice of you. You are surprised as they open fire at you.
Cade, Lia, and Lorahzt (and anyone else who wishes), roll for initiative! (Lia and Lorahzt can take their turns now, the rest of you must wait until next turn to do combat actions.)
Goblins initiative: 4

Lia’s initiative: 9 

Lia watches Cade sneak forward, and catches a glimpse of movement! It’s goblins! She draws her bow and fires at the goblin closest to Cade:

Attack action (short bow): Attack: 25 Damage: 9 

((OOC: I rolled with advantage because the goblins haven’t seen me, is that right? If not, just use the first roll?))

Ologu’s Initiative: 6

Ologu hopes that during the surprise round he can both verify that Nix is securely (I.e. painfully) tied to the tree and the range of the two new goblins.

Lorahzt's initiative: 15

Alongside her fellow elf, Lorahzt raises her longbow and looses an arrow at the furthest of the two goblins.

Thror's Initiative:22

Lia letting off an arrow alerts Thror to the danger, magical energy building, he gets ready to meet their foes.

Cade initiative: 8

Arame is still looking through Sally the owl's eyes into the cave and she is unaware of any danger around where she is sitting beneath the tree. 

(Lia, I'd say that by extension, the goblins have probably seen you as well.)

Lorahzt's arrow is aimed perfectly, but the goblin it is aimed at ducks behind the thicket to avoid the arrow. The goblin Lia shoots at is not so lucky, being distracted at a fatal moment. The arrow hits it straight in the chest, and it immediately collapses over, dead.

The other goblin, as mentioned earlier, aims its shortbow at Cade and fires. (Attack: 11 Damage: 5) Seeing its companion dead, the goblin will then disengage and move away from the thicket.

After bringing one of the goblins down, Lia tries to gauge what the other goblin is doing and where it’s scampering off to...

Arame's owl, Sally goes as far into the cave as she can without disconnecting from Arame.  

Do I see anything else? Otherwise, Sally comes back and lands on my shoulder and I look up just in time to see Lia kill a goblin. She is confused, not knowing whether this is the same goblin who had been giving them answers or a different one.

(Let me know when it is Cade's turn.  His action will depend on where he is when his turn comes around, in relation to the enemy.)
