Jebs Lucas was the clan leader of the Lucas Clan. He was the current owner of the war blade, Slaughterer, the ancestral heirloom of the Baruch Clan, before Linley Baruch purchased it from him. At first, he was rather unwilling in selling it, and only agreed to sell it for 600,000 gold coins, because it originally belonged to the Baruch Clan. It was still a lot cheaper than the 1,000,000 gold coins it was worth.
However, after Linley became famous as a Grandmaster Sculptor, he almost begged Linley to take it for free, due to his great admiration of sculpting. In the end, however, he was still paid 400,000 gold coins.
