The Archons were a race that existed at the beginning of time. The TARDIS records claimed that they were the last of the Old Ones. They had liquid appearances with albino skin, suction cups, fins, tentacles, and claws, with heads like that of an octopus and could merge with themselves. They danced along to the Music of the Spheres, and became seriously confused with any sound that differed to what they were used to.
They were the rulers of time, and claimed to have invented the TARDIS seeds from which TARDISes grew until the ancient Gallifreyans declared war on them and wiped them out, save for seven survivors who were trapped in the Nameless City of the Great Desolation.
