Varoht

Varoht is a term used in speculative fiction and world-building to denote a reversible or counter-causal phenomenon. Because it is not tied to a single canonical source, definitions vary by author and work. In general, varoht is described as either a latent force that can invert events, a boundary state between states of being, or a practical mechanic that allows controlled reversals.

The word is a constructed term with no standard etymology. It appears in multiple independent works and game systems; some authors derive it from a fictional language where roots evoke sight and reversal, while others treat it as a symbolic coinage.

In fiction and media, varoht may be presented as a mythic or occult force accessed through ritual or specialized knowledge. In games, it is often a resource or mechanic that lets players undo actions within a defined window or alter outcomes retroactively.
