>see part 1 here< part 2 of my theories!
at this point andrew has entered the Facility and is destroying himself in order to get to the top. he's gaining more information but also becomes for ignorant. i believe that is why he made the mistake of falling for smiles trick. so he's more conscious and aware then ever but his heart is dying because he chooses the mind over it over and over. and when he jumps into the void it all resets.
3. the void. now, if my theory is right, the lowest layer is the least consciousness one. it can only be accessed from the top when you know of its existance. while the protocols allow you to send yourself/others a layer down (tha katabasis chris did to andrew sent him from memories back to the overworld) or up (anabasis) thats doesn't apply the void. i'll touch more on the methods of going through the layers later.
it appears to be an empty world. there's only a basis: the terrain (generated the old way btw) and the trees that are a bit uncanny but serve their purpose i guess. in the teaser we see more structures: a staircase, a computer, a house-like structure, something like a fence pen, a cave(?). all of them are pretty primitive. looks almost like someone trying to recreate something from memory but it isn't quite right.
i would also like to note that the trees are probably artificial because trees never generated in this shape, even in the older versions. it is the same shape as the tree in smile's tester though.
what do we make of all of it? honestly im not sure. i can theorize that those are the structures smile left behind since we know for sure he was there.
^ this journal also confirms you lose your memories by descending there. and it's not just the katabasis protocol effect, bc andrew remained mostly himself after undergoing lethe, while ev, well, became smile.
it's unclear if chris had been to this layer before, but id say it's unlikely.
4. wells&doors. there's currently three ways to travel between layers: wells (only going up), protocols (which there are more of then katabasis and anabasis only and not all of them include losing memories), and doors, which chris uses. we know that wells(their properties) were there even before ev, protocols, partially, were made by smile and doors have unknown origin. chris didn't build them, judjing by "this place again?" and smile can visit the door dimension ("i should be quiet here"), but for some reason it appears to be chris's corner of peace. my theory is that the land of towers and the door dimension aren't their separate layers, but more of just tools to travel. the wells are like taking a (one-way) staircase, while the doors and protocols can be concidered elevators.
5. lastly, there's more questions to be asked and analysis to be done. for example why does anabasis require layer 4 action (admin permission) when katabasis seemingly doesn't? maybe it simply doesn't show up in the logs when chris runs katabasis. the teaser basically tells us that anabasis failed to run, whether its because smile interrupted it or because chris didn't have enough admin permissions. so now they're both on the lowest layer. now we can only see how it's gonna unfold.
