The tunnel leads to a staircase.

The air down here feels a little colder.

loot and scoot.

You find three gold coins to loot and a chisel!

With our engraving skill we could leave behind some kobold wisdom for the dwarves to find. Such as an illustrated guide to sneaking, e.g. successive pictures of us performing a flawless dodge and roll.

You engrave all three steps of a sneak-dodge-roll maneuver onto one of the blank tablet.

I vote for another draw-and-post for the tablet! Like the barrel! Also, continue looting things! Be sure to scoot!

You are about to finish filling the tablet when you hear noise coming from the staircase.

hide in the stone coffin

You hide in the first place you can find which is the broken stone coffin.

Someone has entered the catacombs.

But you make it inside before you are spotted.

You grab the amulet and hang it from your neck. You brace yourself for a surge of hulkish power but nothing seems to happen. Strange...

You hear the dwarf's foot steps become fainter so you take a peak.

The bandana clad dwarf has gone deeper into the catacombs.

Carefully sneak behind the dwarf to try to see what he is doing, then possibly return to your mission of helping them deal with the elaborate defenses around the lab.

You sneak to the next hallway to check on the dwarf.

Um... Okay then. It doesn't look like this tunnel leads to the labs. Maybe it's time to head back.
