Lost Courier

I think I’ve seen you before. You’re the legend, do you know that? Your story is taught in schools! Another secret mission here, eh?
We’re not beating about the bush here, you know. We’re setting up links with Catherina. But she doesn’t seem to be loyal to the Leage. She only wants more power, that’s it.
We have a secret mission here. I won’t tell you what it is, you have to understand. But I will still ask you to help.
One of our couriers had to arrive, but there are lots of Catherina’s soldiers around the spot. We laid down a couple dozens, but they might return.
Go to the meeting place, activate the beacon and get the message. You are out of suspicion.

Where’s the Ciphered Message, eh?

Wha-at? Guards came instead of the courier? You must be kidding me! Look me in the eye!
You’re not lying then, eh? I can tell by the eyes. So our courier got converted, gave us all out, eh? Just you wait, if Catherina hasn’t got him yet, we will surely dig him under ground ourselves!
As to you... Oh screw, we Imperials are loyal to our word, no matter what. Listen up.
When we set up here, we came across an old grave. Our scouts reported that there’s an old demon buried in it. The very same demon that defeated your Skrakan! So, they found the entrance to the grave wide open, and tracks all around - traces of real big feet!
We didn’t go in. Why should we? I’m sure these tracks belonged to them iron knights. Who sent them there? Your guess? Could it be Catherina, eh?
What would the Queen look for in the grave? She wants to set up no wine cellar there, for sure?
Don’t talk too much, though. You’ll be risking your life if you do. You never saw us, we never saw you. I promise to shoot you, if I ever meet you again.
