Grand Master Perior was the leader of the White Knights during the Fifth Age. He, alongside Lord Valzin of the Kinshra, helped King Raddallin unite the 22 tribes of the Asgarm and found the nation of Asgarnia. He was declared the saviour of Falador by the Council of Falador, and was gifted a magnificent sword to honour him, which did not sit well with King Raddallin. The king believed it to be an act to embarrass the Kinshra, so had a similar sword commissioned for Lord Valzin.
- His name, when given the usual "sir" affix for knights, is a pun on the word 'superior'.
