Harmonia Nectere Passus derives from the Latin word "harmonia", meaning "harmony", the Latin word "nectere" which means "to connect, join", and "passus", which may come from the English word "pass". Put together, all of this could mean "Connect and pass (or transfer) in harmony." Basically, binding the rift between the sister Vanishing Cabinets.
