Andulvar Yaslana, known as the Demon Prince, was an Ebon-gray-Jeweled Eyrien Warlord Prince who served as the Warlord Prince of Askavi and later, as the Master of the Guard of the Dark Court. He was a long-term companion and a friend of Saetan SaDiablo, who regarded Andulvar as his brother. Not even Hekatah SaDiablo's schemes managed to diminish the bond between the two Warlord Princes. Andulvar had a son, Ravenar, with Hekatah. Prothvar Yaslana is also his grandson. Later Lucivar and Marian named their second son in honor of Andulvar.
