Kae:
As the group looks on Kae opens the package with her knife. It takes some doing as it seemed the "sender" did their best to prevent the contents from being damaged.
Kae pries the lid open and is almost blinded by the magical light coming from the contents, 3 small vials of liquid, 1 blue, 1 yellow, and 1 pink.
Kae also finds a note inside.

Eddie and Zal:
After seeing that the "treasure" Kae seemed so excited about was only a couple of test tubes with odd-colored liquid in them, you both sit by the door prepared for whatever is coming your way.
The waterfall makes it difficult to hear but you are able to make out the sound of dragging footfalls kicking up gravel, like someone who drags their feet when they walk. 
They sound like they are getting closer and you start to hear what sounds like humming.
Up the stone steps near the waterfall, you see a figure walking towards you.

Zal:

. 

After a bit of squinty, Zalos eyes go a bit wide with confusion. "A... Is this half-orc freaking mental?" He whispers more to himself than anyone else, but then side-eyes Eddie as he more pointedly but quietly asks,"What's with the Spaz? Friend of yours you forgot?" The half-elf otherwise looks conflicted between wanting to stay on guard or relax and try to get the half-orcs attention.

But as a more sinister concern began eating away at the back of his mind, Zal took on a more guarded posture but otherwise appeared content to wait until the half-orc blundered into potential poking range with his spear. "Or maybe... He's Klarg's contact with the redbrands."

Kae doesn't seem to pay much attention to the approaching creature. She figures, whatever it is, the boys will keep an eye on it. "Ooh, potions!" She quickly reads the note attached to the package. "Looks like some kid got a job. Good for them! What did they cook up, though?" She takes off the glasses so that she can see the liquids more directly, then attempts to identify them by their color and weight and such.

 Arcana deals with Lore on magical things but can not identify them for you. 
You did have a "mysterious" pink liquid in your pack that brought you to your present state.
As for the rest, unless you have skill and access to an Alchemy lab or an Identify you can not narrow down what each potion actually does.

1/2 Orc Perception roll: 22

 The Half-Orc stops in his tracks, his head whipping up as if he saw something, and spins around and runs.

"Hold up my man." Eddie yells as he starts to give chase. He holds up his fingers in the Vulcan salute "We come in peace."

As Eddie calls out it seems the half-orc doubles his efforts to flee the area. 

Eddie rounds the bend in the tunnel to see the half-orc just leaving the tunnel entrance. 
You know it's a long hike back to the closest road, at least the one you drove in on, so either he has a long way to go or there is another trail close by. 

Zalos clicked his tongue, but a moment hesitation in wanting to see if Eddie's words might be heeded lead instead to him giving chase after the fact. However, he stops just short at best only thirty or so feet away from Klarg's chamber, as his consciousness over leaving Cornchip (and by extension Kae) behind, as well as the whole run around the "spirit" gave the group gets the better of him.

"Yo Eddie!" He calls out at a stage whisper in leeriness of his voice echoing too much. "Let chicken little run! We'll track'em down later!" Zal continues, hoping to having caught the shifter in time. No matter what comes after, though he would be a bit sour faced if his word hadn't quite reached Eddie in time, he doubles back to Klarg's room and says to Kae. "Head's up. Some half-orc chicken flew the coop. Not sure if they'd actually know a thing or not, but if ya done thumbing the loot, might be time for us to move on one way or another. Still got the gobby on the other side to put the screws to 'fore we bounce."  

"Gotcha. I don't even know what I'm doing with these things, I definitely can't tell what they are, except that they're some kinda magic. I suppose there's only one way to find out. Well, two ways. More like four. But that's beside the point. Wait, what's the point? Oh right, we gotta get going. Gotcha." Kae stands up and begins tossing her augmented rocks between her hands. "Well, lead the way."

Eddie will proceed to the tunnel entrance to see if he can gauge which way the half-orc is running but he won't exit the tunnel without his friends.

Perception check: 19

Eddie gets to the end of the tunnel. It opens to the world outside. 
He signs. It's raining again.
However, he does not see the 1/2 orc. He does see where it passed in a hurry but that trail disappears around the corner and possibly into the bush. 
Zal and Kae catch up soon after. 
The party gathers at the end of the tunnel. 
DM:
Zal has found a ledger book that indicates a place called Phandelver.
Kae has found a box with mysterious magical liquids that has the shipping address of the same small town. 
You have a decision of what to do next. 
You could pursue the 1/2 orc, where ever he has headed.
You could turn and make the trip home, putting the tragedy of Sully's death behind you.
Or, you can travel to this town, Phandelver, and figure out what connection it has to this mine, the goblin gang, the stolen packages, and the police officer that was held here. 

What do you do? 

"Oh for crying out loud, what is this?"  Zal complains softly as he looks out to the rain. "Did Tempest really had to take a piss again?! Or-" He trails off groaning and pulling at his face. "... Well if we're gonna catch up with Chicken Little in ANY capacity, we gotta start making tracks 'fore  the rain washes his trail away altogether. But honestly I... if that turns into another goose chase, I honestly don't know what I'll do to the punk." He admits as he looks to the ground with his hand balling up into a tight fist.

He then takes a breath before continuing, "Honestly, I have half a mind to go back in and kick in that gobbies teeth 'till I get more answers. But odds are he don't know squat, and I'd -- we'd be wasting time. So, that just leaves Phandelver." At this point he finally looks to Eddie and Kae. "I'm going there, and I'm getting answers one way or another. And make sure the gang or gangs wrapped up in this whole business pay in full for messing with Family... But that said, I... could of course still use your help in all this. But I'd understand if you two have had enough, and are okay with whatever, uhh..., closure you got from coming this far."

"If going to this Phandelver place helps us find out who is responsible for what happened to Sully I'm definitely in. There's no way I'm going back home. If these guys were up to something dodgy putting a stop to that will mean Sully's sacrifice was worth more than just saving some cop who dropped us in a motel and then booked it."

"I'm definitely not leaving things here. I mean, the bastards got Sully! Sully! I'm not gonna, like, twiddle my thumbs and hope everything works out. And anyways," Kae motions to the box of potions, "I wanna get these things to the people they were addressed to, which just so happens to be in Phandelver." She takes out her car key. "Do you have a car? There's plenty of room in ours."

Eddie:

While pondering all these things the party makes its way back to where Kae and Eddie parked their car. 
They climb in and Zal follows with Cornchip in tow and the party sets out.
(if there is something else folks want to do, let me know)
The rain does not let up and the overcast darkens the sky, giving you visibility of only about 40 ft.
At one point you start seeing blurred images on the side of the road as you pass. 
You turn off the main highway and start heading east. The road, a well-maintained 2-lane with a middle turn lane, quickly turns into a small 2-lane country road walled by pasture land and wire fence on one side and trees on the other. 
There are few houses and farmhouses here and there but soon they become scares. You occasionally see road signs:
Phandelver 30 miles
Eldermath Orchard 20 miles
Phandelver 15 miles
The rain lets up slightly as you top a hill. Looking over it you see the road ahead as it winds down about 5 miles to a small forested valley. Nestled in this valley you see street lights shining through the foliage. To your left, you see the sign:
Welcome to Phandelver
As you travel this last leg of your journey you count 40 or so buildings that make up this small community. Your passing car lights shine upon several old, dilapidated buildings as well, some full buildings some just partial walls.
The clock in the car points out that it's about 9 p.m.
Getting to the bottom of the hill you find no traffic nor anyone out and about. 
The road you are on leads to a stop sign in the middle of the town. As you stop, you look left then right. The only thing that appears to be open is what looks like a bar. A blue neon sign flashes in the front window:
Stonehill Inn
The sound of Old Country music can be heard coming from the bar. 

Kae pulls the car over by the side of the road, near the Stonehill Inn, and turns it off. "I dunno about you guys, but I'm pooped. If this inn's actually an inn, it'd be a good time to catch some Zs. Unless either of you wanna sleep in the car, that is. Which personally I'm not super opposed to, but it kinda feels like we deserve actual beds." She gets out of the car, expecting the others to do the same, and leads the group into the inn with the intent of purchasing a room.
