“I asked six wanderers about Level 4 and got six different routes. None of them had been.”
Level 4 is the gap on the map that wanderers point at. In the tradition of those who go down, there is a fourth level behind the three the archive has walked: Level 0, Level 1 and Level 2. Nobody has mapped it whole. This entry gathers the little that repeats across the accounts.
The archive doesn’t write it off and keeps it open, so the gap doesn’t look like an oversight.
What people say
Some say Level 4 doesn’t belong to the continuous terrain. You can’t walk there. You enter and leave through doors, and the trip has no continuity with what you leave behind.
The place would be a set of rooms connected by corridors. According to the accounts, that set changes shape every ten minutes. Everyone inside sees the same layout at the same time, with no need to agree on it. The room you are in stays where it is while you occupy it, and everything else rearranges around you.
Some testimonies add that it is a bounded place, about a hundred and fifty meters on a side, and that you can’t build inside. Those who took shelter there swear the presences were more numerous than outside.
How you get in
There are two versions that don’t contradict each other. The first says the door stays open for about five minutes. The second says that whoever overstays comes out far from the point where they entered, about a hundred meters farther for every minute of delay. Nobody can say who measured those figures.
Clues found
The sublevel Level 0.0 holds an exit that, according to several wanderers, points to a Level 4. The floor notes mention it in passing and never with a route.
A longer report covers how the epochs work in Level 4: reserve and epochs.
What to do if you find it
If a door takes you to rooms that change without you moving, don’t stay more than five minutes. Keep the point of entry close and warn your group. And write down everything you see, because this archive needs it.
