'''Explorator Binary''' is very similar to [[Techna-Lingua]], the [[binharic|binary]] language of the [[Explorator fleet]]s has diverged from its parent tongue; the Mechanicus permits its use, but frowns on it for official discourse. [[Questor (Adeptus Mechanicus)Quaestor|Questor]]s and other field operatives use it to keep conversations private from their planet-bound brethren.{{Fn|1}}
