Scholars of the University of Rago Rago 56 Rago

The Scholars of the University of Rago Rago 56 Rago were four scholars of the university of Rago Rago 56 Rago.

They wore white robes. Two of them had gold, metal faces while the other two had faces that resembled tree stumps.

They visited Platform One at the end of the world in the year 5,000,000,000, with the result of 27 A++ scores of their intelligence at the Rago University. Due to Lady Cassandra O'Brien's sabotage of the space station, one of them died from the heat created by the Earth's destruction. (DW: The End of the World)

The Scholars, along with the other survivors of Platform One, were later kidnapped by the Elth of Balhoon, who believed that they hadn't tried to help the Moxx of Balhoon and had abandoned him to die. They were rescued by the Doctor, and not only forgave the Elth for kidnapping them, they offered to help him. (DWBIT: Reunion of Fear)
