First Appearance: WB2014 Digdoug - Episode 2
Duke Eften was a Noble Warlord from Delkey assigned to defend Weatherbug with a small contingent of Infantry. He was a bit snobby, and believed Homekey and its units were too rustic in their sensibilities. But implicitly accepted Prince Creen was a fop. He was croaked along with Lady Allison Chains defending the city.
