Etymology
The ability's Japanese name, "Solo Arcanum", translates to "Only Secret" in Latin. Its English name is a pun on the Japanese name and "Ars Arcanum" (Latin for "Secret Technique"). As such, it is meant to mean "First Technique". "Solum" can also be read as "ground" or "earth" in Latin, playing on Terra's own name; as such, "Ars Solum" can be read as "Earth Technique".
