"Finally the lab is almost complete. Security measures have been put in place so the chance of detection by the Americans is very unlikely. We also have several agents embedded with the staff as insurance. We will keep the individuals in stasis, on ice to speak, and continue the specimen rotation once we finish drawing more power from the drill . Oh, I almost forgot, the sequencing for the current blood samples is as follows: SSMJABR"

Cipher #2

This cipher is written in Octal.

The plaintext is as follows:

"Reality or Dream it is becoming harder and harder to tell. He came to me again last night while I was on my nightly walk through the countryside.

The plaintext is as follows:

After I am done here at Morg City, I have to head to San Francisco to interview "the subjects". The idea of being trapped in that prison gives me the creeps."

Scrap Papers

There are three scrap papers around the map. One of them is a code written in Microsoft Macro Assembler. The other two scrap papers are data to enter in the code.

Scrap Paper #1

The plaintext for the first message is as follows:

"My name is Pablo or at least I think it is or was I don't know anymore. I have been locked away, held prisoner in this cell for many months by Germans scientists. They keep experimenting on me, pumping me full of some blue liquid. I think it is responsible for the repeated visions I have been having which I swear look and feel real. In this vision, my name is Pablo Marinus and I am a knight coming back from the crusades. I fight in a great battle against strange demon like creatures who are trying to devour the Earth. At one point, it appears I am doomed, trapped in the tentacles of a great three headed beast when suddenly four knights decimate it with magical elemental staves, saving me from certain death. There are otherworldly creatures that fight on our side against the demons. The creepy thing is that the sigils on their tunics resemble the one I noticed on stones here at the castle as I was being brought to my cell. I just hope I can eventually find a way to escape this place."

Scrap Paper #2

The plaintext for the second message is as follows:

"While I consider myself to be a brave king in battle, I will tell you my son that those four were the bravest warriors I have ever seen. I had the privilege to fight alongside them in the great battle many years ago where we defeated the creatures from beyond and the dead eaters. They disappeared after we claimed victory never to be heard from again. The last thing they told me was to build my castle here in this very location before they disappeared."
