The RDC is a non-profit organization in the Viperius Galaxy. The acronym stands for "Rift Detection and Control". As the name suggests, they located and contain Dimensional Rifts.
The organization is based on Centro.
Much of the detail about this organisation is classified. However, it is known that they have relatively few personnel.
They have several high-tech spacecraft to allow them to travel to the planets on which rifts appear.
The RDC was founded by the Salsene Kyrt Vonne, who was injured by a rift-traveling Therizinocitatus at the age of sixteen.
