Grimvault Expedition of Discovery
Day 21

Although it seems clear to even a casual observer, I cannot stress this enough - the current Grimvault, the disease-infested universe of corruption and Strain, was not designed with anything like this in mind. The Eldan did not leave this place like this. They wanted the Strain confined, and Grimvault itself was more of buffer zone. Now the buffer zone is filled with Strain, and it's only getting worse. All technology in this area, while Eldan and therefore mysterious and strange, nevertheless served a purpose, one the Eldan took with them when they disappeared. Now that technology has been compromised by the techno-phage.

Day 22
Although this Ethereal Hollow resembles a natural formation, I'm beginning to think nothing in this Grimvault is natural. It is completely saturated with corruption, and this underground network is no exception. What purpose did this corrupted complex serve? Was it, as some have hypothesized, the site of the Eldan's downfall? I must dig deeper.

Day 23
Dead. Most of them in the latest attack. The corruption all around us - it is coming to life. The Strain... it thinks. Walks, talks, and fights. It is intelligent. And it hates us.

It walked, it roared, it snarled, it killed. It wants me... us. It is not just a substance. It is thinking. It wants. It needs.

It kills. It wants me to kill. It wants me to join it. They want me to join them. I... we... will join them.

We will kill.
