Technohymmnos, also known as Toumyounokisakinogengo (灯冥后の言語) is a fan made language by Sonwe Ruolmi based on the Hymmnos language created by Akira Tsuchiya for Ar tonelico video game series. This language is used by the Public Domain Song Server. It was made to enhance the power of a Reyvateil greatly, allowing Songs with faster and stronger execution. A unique feature of the PD Song Server is the "No-Control Policy". Basically, any Reyvateil can achieve the stats of Administrator temporarily through the Unisphere, even Third Generation. Another feature is the "Trust Program" which allows Reyvateils from other Servers to establish a connection and use the PD Server freely, along with the Technohymmnos
