Enemies

The Time Keeper

 * The Beheaded encounters a crossing area with a series of giant floating swords, with a few weird conditions and physics attached. It seems to be somewhat disturbed by them. Upon opening the door to a room, it feels "Like I'm floating, as if everything was speeding up and slowing down at the same time."
 * A letter left by the Time Keeper indicates that she is repeating the same day over and over, as if time was rewinding every day. Indeed, the Time Keeper keeps track of all the infected people and monsters she has executed, but all her entries are classified as "Day 1". It would appear that this task is quite taxing for her, as the number of people and monsters executed per day lowers.

Alchemist grimoires

 * A grimoire by the Alchemist reports he found a formulation (which likely includes the Sanctuary substance as base ingredient) that slows down the mutagenic effects of the Malaise.
 * A guard's room contains a note which states that the guard is going to attempt to talk to the Alchemist about evacuating due to the rampant illness. The note is cut off before the word "Alchemist" can be finished. Behind the room is a secret alchemy lab.

Other rooms

 * As with most biomes, there is a chance of finding a lore room with a bonfire, referencing the game Dark Souls. When you interact with a sword at the campfire, The Beheaded will say "The campfire was abandoned by an earlier visitor", "It won't hurt if i stay here a little" and "Something has changed". Words written on the wall spell "GIT GUD" when interacted with, and the dead man will give an item with some gold. An enemy will sometimes appear in the room, and will drop a lot of cells upon death (50 at 1 Boss Stem Cells).
 * You need the.
