After acquiring the Relics (except for the Greaves and the Sword of the Crusader), Lathon will arrive at the Priory of the Nine to give the Hero the Greaves. He will explain that Sir Roderic had discovered the resting place of Sir Berich, who took the greaves and the Sword of the Crusader with him to war. When they arrived they were attacked by Berich's Wraith, now known as Lord Vlindrel. Sir Roderic sent Lathon away with the greaves while he held off the wraith.
After finishing the Knights of the Nine questline, Sir Lathon can be recruited as a follower, but it is possible for him to be killed while accompanying them. If this occurs, he will be replaced by a Knight of the Nine.
"I am Lathon, squire to Sir Roderic of Wayrest. We are on a holy quest for the Crusader's Relics!"
- Crusader's Relics "Surely you've heard the stories of the Quest for the Crusader's Relics? Only a true knight can find them -- or even wield them. Sir Roderic will surely succeed, if anyone can."
- Sir Roderic "Sir Roderic is a famous knight of Wayrest, in High Rock. He is too modest to tell you himself, but he was a hero of the War of Bend'r-Mahk."
- Didn't Wayrest lose that war? "Well ... yes. But Sir Roderic won many battles all the same. I'm sure if we had more knights like him we would have beaten the Nords."
- I'm sure he's a mighty warrior. "He is! I've been his squire for almost two years now. Soon I'll be ready to return to Totambu and become a Knight of the Scarab."
