Query: Aspects of $C^0$ causal theory   This paper serves as an introduction to $C^0$ causal theory. We focus on
those parts of the theory which have proven useful for establishing spacetime
inextendibility results in low regularity -- a question which is motivated by
the strong cosmic censorship conjecture in general relativity. This paper is
self-contained; prior knowledge of causal theory is not assumed.
