1 - The missing villagers of Tar

There's been a lot of passing through this tunnel recently going from the small tunnel on your left toward the entrance and the northern passage (and the other way around).
But you are unable to find any clue that would confirm that the prisoners you are looking for came here.

If you can attempt to harvest two things : the upper shell, hard and large enough to make a piece of armor if assembled ; the very thin back legs, pointy and solid. That would be a Dexterity (nature) check of DC 15.

As Chathum, Jacques and Tianna are talking on your next steps, Mee'haïl seem to be dissecting your attackers. Two minutes later, when his done, he comes back to you with his hands covered with yellowish goo from the creatures.

Having spent some time at this intersection now, the initial nausea from the smell has passed leaving only on vague discomfort. You start to adapt to the darkness of the cave too, but the absolute silence found here still unsettles you.

You hoped that heads would come up, but Fate spoke. You'll go into the webs. This is a narrow passage and you'll have to do it in a single row. In what order will you walk?

Each time your torch touches a new patch of cobweb, it burns in a flash just like it did while you were fighting the arachnoid creatures. You quickly spot that, if those thin webs are easy to inflame, the huge string that comes out of a big hole in the wall and runs into the passage —just like the one you spotted earlier— doesn't. Probably something to do with its apparent moisture.

In the tunnel, the stagnant air smells feels like it is impregnating your clothes and hair. The stench gets stronger as you advance, until you spot its source : lying on the ground in an even smaller passage on your left, you find two human shapes rolled up in spiderwebs with a big webby egg attached to them.
The one closer to you was apparently the object of the fight you overheard, having one of its legs missing and other visible bites on his rotting body. The second one appears to be in way better shape, either protected by one of the spiderlings or saved by your intervention.

On your right, a similarly narrow tunnel goes up and turns right at the edge of the light from your torch.

They are moving you. Again. Will it hurt too? You can't wait for it to just... end. But wait, what is it? Fresh air, voices!

The cocoon is robust, somewhat sticky, but pretty clean otherwise. As Tianni cuts the prisoner free from his prison, he starts to breath again. Barely at first, then he takes a deep breath and seems to regain consciousness.

Bug, it feels like you just woke up from the dead: you feel weak, nauseous, and have a hard time to even try to get up. You can't see or hear very well yet, but it comforts you a lot to feel hands on you. Your left shoulder hurts a lot, you'll have to look into that. Fortune in your misfortune, it seems like they rolled you in that cocoon with most of your stuff. Your waterskin has been perforated, but that's about it.

The first egg, the one attached to the dead body, has already hatched. By the size of the egg you (Mee'haïl) guess that what came out of it probably was one of the spiderlings. The second egg, on the other hand, doesn't show any sign of being at term. By cross-checking your observations with the damaged corpse, you an tell that it take about a week for the egg to hatch and start to eat the body.
