Archivian

Archivians were a robotic library interface who served the archive of Islos. They were led by the Chief Archivian.

When the Daleks came for the archive, the Archivians were left to protect it. The Chief Archivian refused to surrender the archive to the Daleks until the surviving population had gone through the portal along with the contents of the archive. When the Daleks captured an empty building, they exterminated all the Archivians, except for the Chief Archivian. (WC: The Archive of Islos)
