Incommunicado - No More

I've just returned from a week in Arundel. The previous day I visited a pub there with a rather enigmatic name that turned out to have a rather innocuous origin, but then I caught sight of a quote on the wall that suggested otherwise. I won't divulge exactly what this matter was but I will provide a translation of the quote into the language it was meant to have been spoken in. See if you can deduce what I mean.

Enigmatic figure: Kothen. Kothen. I lan ma, vahl?
Kothen: Nahl. [figure reveals its true nature] O! Vahl, ma rah, A lan mi!
