Lambor's Hold

As you all take a rest, you recover and find some new strength in yourselves. Eventually, when the weariness from the battle has worn off and you are already getting ready to get up again, Auras, who has been keeping watch, notices a single blue-skinned fey peek out of the cave entrance.
When she points it out to all of you, it's not hard to guess what it is doing: It's trying to find out if you are still around or have left after the fight. It hasn't noticed you yet.

As Auras approaches the mine entrance, the fey clearly spots her and turns to run back inside when Arphaxad's loud voice roars out, claiming that your group is leaving. It makes the fey pause for a moment.

Auras steps on a branch as she tries to close in on the fey peeking out.

The fey turns towards her and it seems like it's just about to spot her when Arphaxad distracts it with his calls. The fey looks in his direction, seems to think for a moment and then breathes a visible sigh of relief. It really seems to have bought the bluff.

The fey pauses another moment, then walks out of the cave towards the closest of the many dead bodies strewn around the clearing and carries it inside the cave where it will most likely report your departure.

After the fey has disappeared into the mine again, you give it a moment and then start sneaking towards the entrance again, moving slowly and carefully as to not make a noise.
You very slowly sneak into the cave, following its slope downwards. You pass a very rugged spot where many large rocks and boulders are lying strewn. This must be where the mine used to be collapsed but is now open again, presumably due to this earthquake you were told about. Eventually, you hear sounds ahead, frantic voices talking in that strange language that they communicate in. There is also a strange, blue glow coming from up ahead.

Arphaxad doesn't recognize it himself but I assume Belathor shares the information with the group.

Narissa meanwhile scouts ahead of the rest of the group and peeks around the corner to where the voices are coming from. A group of fey are gathered in a small opening in the cave, almost a room. There are glowing mushrooms illuminating the walls and old blankets are strewn about. It looks like a very uncomfortable, improvised sleeping chamber.
The elven woman is with the fey, talking to the one you recognize to be the leader from the surface.
In one corner, there is a large, rectangular object covered by a number of blankets. The shape is that of a box of some sort, large enough for multiple people to easily fit into it.
