Clock Tower

"The Time Keeper hasn't been seen for a long time. Or else very recently... Uh, wait a minute... When is now?"

The Clock Tower is a fifth level biome. It appears as a very tall tower which splits into more ends as you get higher. Windows, gears and trellis make up a big part of the environment. It is the only biome that develops itself mostly vertically. It expands only upwards with an occasional branch to the side.

It can be accessed after finding the Village Key in one of the upper rooms of the Stilt Village. This biome can also be accessed from the Slumbering Sanctuary.

Lore Encounters

 * 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.
 * 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.
