As you explore your surroundings you discover a massive, sealed door. Try as you might, you’re unable to open it. It’s far too large to force open, and whatever mechanisms once moved it seem to have grown inert.

Search the general set for the Locked Passage and put it into play.

As you inspect the door further, you discover that a critical component appears to be missing—a power source. You spend a few moments rummaging through your gear, but find nothing compatible with the Estian technology. If a replacement power source exists, you're certain you'll find it down here in the arcology. But where?

The moment you have the thought, you spot something at the foot of the door, covered in dust: a note scrawled in a hasty script.

"I couldn't wait any longer. I'm going beyond the flooded passage, beneath the main artery, to the chamber where the Estians once slept. Don't worry, Hollan, I can handle myself. —Timo"

You recall that Hollan was the name of the leader of the lost expedition. Perhaps if you follow, you'll learn of the team's fate.

Find where the Estians once slept.
