The Battle of Wasted Years occurred by 1032 BBY. The Sith Lord Darth Krall participated in the battle and emerged victorious. The story of Krall winning the battle was included in the holojournal of Klias Teradine, a Jedi Padawan during the High Republic Era who was killed in 241 BBY by fellow Padawan Tylera Yorrick after he had become possessed by a vitalicron, though he was later theorized by many Jedi to have been expelled from the Jedi Order.
In 88 BBY, Jedi Initiate Sifo-Dyas told fellow Initiate Dooku about Teradine's holojournal and its information on Darth Krall's deeds, including the Battle of Wasted Years. Dooku later told his sister Jenza about their conversation in a holo-letter. Around 23 BBY, Dooku gave data disks containing his messages to Jenza to his recently recruited Sith assassin, Asajj Ventress, for her investigation into his sister's location, and she listened to the message that mentioned the battle.
