Faustus quickly bolted through the door and as soon as the armored one was through he slammed the door shut. Working quickly, he took a vial of salt and a red berry from his robes, pouring the salt in a semicircle around the door and muttering to himself in a long forgotten language. He then took the berry and crushed it against the center of the door, painting a small rune on the door with the juices.
"That should hold it, at least for now..." Faustus said, tired and a bit annoyed. "Unfortunately the entity you killed was more or less a prison for something more powerful." He said to Gawfy. "Oftentimes Greater demons will trap their rivals in flesh constructs. Such creatures are often nothing more than raging masses of limbs and teeth, which would explain the being from earlier. Hopefully, whatever was trapped inside it hasn't gone insane due to its stay in the creature."
