The L-Value is an object within hell created by The Archangel. It is a destructive artifact which can set any universal constant, including time. It is visually indescribable and can only be manipulated with an extremely large amount of Dark Energy.


"L-Value" is a reference to the C programming language's concept of lvalues, which are values that can be used on the left-hand side of an assignment operation.


In lithium, The L-Value is used to create a time-loop to gather large amounts of extraneous Dark Energy from the events that unfold within the 20 years Lithium's story takes place in.
