Ospos moves his Dancing Lights humanoid form 70 feet ahead of the party, in the tunnel with the tracks.

Calming himself a little bit, Dril agrees to descend down the ramp with footprints.

"I'll follow you, Liafel."

The first couple hundred feet of the tunnel look similar to the first passage you used to enter the mines: durable dwarven construction, support beams, and occasional writing in dwarvish. But suddenly, an end to the tunnel comes into the light of your spell. The wall ahead is rocky, and thin bands of glittering mineral cut across it. It seems to be the last point at which this tunnel was mined before it was originally abandoned.To the right, another, narrower passage opens up. This one is rougher, its floor and walls uneven. and curves sharply down and to the right.

Ospos looks at the new tunnel and asks the group how to proceed, "Do we want my lights leading the way announcing our presence, or do you all think those who can should try to sneak ahead and scout?"

Frank responds to Ospos,

"I don't think we can sneak very efficiently as it is."

Frank indicates his and the others, torches,

"So possibly springing any ambushes ahead with your glow-man, sound like a good idea to me."

"If you like I could use my "distraction" alongside your glow-man. I'm not very competent with illusion magic yet, but I can make a...disturbing, cat to follow along with him."

Frank sets his face in a serious expression, and casts Silent Image. At first it doesn't look like the spell casts properly, but Frank seems to strain hard and then, pop, an odd looking cat appears in front of him.

The cat is an odd combination of blue/green and grey stripes and as it turns to look at Ospos, it smiles. The smile doesn't seem right, and it's not just that cats don't normally smile. The smile climbs up the cats checks much further then should be possible, and there are teeth all the way to the end.

As the cat is smiling at Ospos, its head starts to rotate to the side, until the head is on its side, still looking at Ospos. But then, disturbingly, the head keeps rotating, it goes all the way around, never breaking eye contact. Once its head is oriented correctly, it turns away and scampers off to walk behind Ospos' Glow-man, like nothing out of the ordinary just happened.

"It has taken me the better part of a 9 months to be able to create and control...that"

Frank indicates the cat now walking ahead of the group, about 10 feet behind the glow-man,

"I don't know how Bram does it, he makes it look so effortless. Me, the best I can do is a deranged cat! I mean, it was supposed to look like a real cat, but that's the best I can do."

"Well at least it still serves its purpose, its definitely distracting."

The Cat:

While waiting for the casters to follow through with a plan, Clermar absentminded looks at the dragon scale. "How big do you figure the dragon this belonged is?"

Investigation 21

Ospos will keep the Dancing Lights Humanoid figure as far ahead as he can given the tunnel (max 70 feet).

"I have a hard time believing dwarves would have done such a shabby job constructing this tunnel"

Dril studies the new passage looking for clues about its construction and looking for traps.

Investigation:13

Ospos elaborates, "And kobolds are known as tunnelers in stories." 

Listening to everyone else's exchange, Frank adds,

"We should be careful then, if this isn't dwarven made we cant rely on it to stay where it is. We wouldn't want to be buried alive down here."

Frank: Your illusionary cat marches on behind the glowing humanoid form, making for quite a strange visual moving ahead of the group.

Clermar: You aren't very familiar with dragons at all, having mostly only heard tales of the powerful creatures. The dragons in most of those stories were said to be immense, gargantuan terrors that ravaged long lost civilizations. Looking down at the vermillion scale in your hand, it's hard to imagine a creature that big would have a scale only a little larger than your palm. You think this must have come from a younger, smaller dragon.

Ospos: You can easily infer that this tunnel is kobold made. While their craftsmanship isn't as aestetically pleasing as the dwarves, you know that kobolds are expert tunnelers, creating extensive underground networks. Scanning the walls of the tunnel, your eyes just manage to make out a small opening near the ceiling a few feet ahead of you, on your right.

Liafial: You don't see anything out of the ordinary, just a dusty old tunnel.

Before delving further into the cave, Dril ritual casts Alarm on the entrance to this new tunnel, set for a mental alert.

"Can never be too careful"

Frank responds to Dril,

"A good life motto to live by."

Turning to the others Frank adds,

"This tunnel doesn't look very big, what order are we going to move forward in? For the larger of us, I don't think we are going to be able to move around each other very easily in there."

Seeing the opening, Ospos looks for someone to do the actual investigating, "Guys, do you see that opening over there, near the ceiling?"  Ospos points for the other's to see.

(just for clarification and cuz I thought y'all were already in the tunnel, the opening Ospos sees is more like 50 ft in, and it's in the wall but up a few feet, close to the ceiling)

Liafial: Getting closer to the hole reveals no tripwires or pressure plates, nothing that would indicate a trap. With your eyes glued to the ground, you don't notice the round object that rolls out of the hole above, flying towards you before crashing at your feet. You see a swarm of squirming, finger sized grubs spray out of what must have been a clay pot. The creatures immediately move for you, beginning to crawl up your legs and look for places to get under your armor. 

Rot Grub Attack: Attack: 2 Damage: 0

You manage to swat a few of them off before they can bite, but more quickly take their place.

INITIATIVE START

Clermar takes out his sword and strikes as many grubs as he can.

Greatsword: 22 to hit, 11 damage

Nean tries to see the "threat" at hand as one collective being. He holds up middle and pointin finger to his temple, helping to concentrate himself, and sends out a psychic burst to attack the grubs.

Mind Thrust: INT save 13 - DMG: 2

Frank calls out to Clermar,

"Careful with that huge sword, you don't want to cut off Liafial's leg!"

Frank Drops his torch to the side and pulls out his Shortswords and tries to cut at the grubs to both kill them and/or brush them off Liafial.

Action: Shortsword attack, mainhand: attack roll: 8; (if hit: 6 piercing damage)

Bonus Action: Shortsword attack, offhand: attack roll: 13; (if hit: 4 piercing damage)

If one of the above attacks hits but doesn't kill the target, then add Sneak Attack damage (max one attack): 1

Ospos yells out, "Get away from that opening before another pot drops!  I'll help you kill those grubs, just move back first."
