Knight's notes are given by the Dying knight outside the God Wars Dungeon. They explain about the godsword and the battle between the gods Zamorak, Saradomin, Armadyl and Bandos and how Guthix ended it. Sir Gerry asks you to take it to Sir Tiffy Cashien in Falador park and asks you not to read it.

My friend, you were right to send me to investigate the dwarf's drunken claims, for I have discovered a treasure beyond our wildest dreams. The aviantese are alive, and I suspect they still guard the Godsword! Beneath the remnants of the temple a great battle is being fought between followers of Bandos, Armadyl, Saradomin and Zamorak. My command was slaughtered and I am grievously wounded. YOU MUST PREVENT THE GODSWORD FROM FALLING INTO THE WRONG HANDS! I do not know how I am going to get this message to you, why is that talking skull never around when he's needed? Your comrade, Sir Gerry.
