Parcel from the Past

Go to Avilon, take the Bag of June Trinkets from Luc de Blizare and bring them to the Wormfaces' cave entrance.

Wow! It seems to me that the ice is broken... I knew that you could cope with the challenge and break the wall which our "charming" allies built to hide from us.
Before you came, there were hundreds of adventurers like you who tried to talk to them through the Talk-back Device. But none of them received a task other than to kill the Undead or to collect samples from poor Crawlers. Then along you come... and you receive a task not about biology which, I must confess, is not my forte, but about history. Well, I know more about history than anyone else! I am a Historian!
So, the Wormfaces are interested in June artifacts... Hmm, what do they need them for?
Let me think. I also have a little errand for you. Go to Avilon to our base camp and meet the Archivist. I wrote him a letter, so he will give you all the June trinkets our association happened to find. There are various beads, color glass, shards... We don't need that crap.
Let's offer the Wormfaces these trinkets and see what their reaction is.

I have already sent the letter to Luc. Your parcel is waiting for you.

Huh? ... What the crap? Some stones, beads... Do we look like butt-naked cavemen?
