It seems they managed to (carefully) lift that thing out of the sarcophagus it was in!

… were you able to tell that that was a byzarian skeleton in there?

 

Also you might remember how the other professor, Queahn, had some issues with that tomb and/or what’s inside of it … but his fears seem to be unfounded. So far.

<A few days later in the jungle, Katharina and Prof. Brahms are looking at the blade from the tomb, which is now kept in a tent>
Brahms: And you are sure that it was a good idea to take it out of the tomb?
Katharina: It seemed very PASSIVE the last days. It showed no signs of activity. In fact it even seemed to ... CALM DOWN once we got it out of that chamber.
Brahms: I'm not sure how good of a sign that is ... but I guess we'll have to trust your judgement on that.
Katharina: It should be fine as long as you keep a certain distance. And DON'T touch it directly. Also someone with telepathic ability will be outside the tent at all times in case it stirs again.

Katharina: ... Professor Queahn really didn't want to take another look at it? I REALLY could use his expertise right now ...
Brahms: He still insist on staying in his tent. He prefers to study ... INDIRECTLY through our descriptions and sketches.
---
Brahms: He also strongly advises that we should ABANDON this site and LEAVE. He demanded that I relay that to you. AGAIN.
Katharina: <sighs> ... noted. Did he have anything else ... ? Something a bit more ... CONSTRUCTIVE?
---
Brahms: Oh yes, apart from that he now agrees with your theory ... the person buried here seems to have had a high position in the empire. But in their final moments they and their following must have experienced some kind of ... SCHISM. We might have actually found your TRAITOR GENERAL.
---
Katharina: Great. Now that leads to ANOTHER question ...
Brahms: ... how this is all possible if the person buried there was clearly a BYZARIAN?
Katharina: ... RIGHT.
