Dark Horse will adapt one of Robert E. Howard's last published Conan stories beginning in May with the debut of King Conan: Hour of the Dragon.

MTV Geek reports the new ongoing series, by Timothy Truman, Tomás Giorello and José Villarrubia, will be based on the 1935-36 serial The Hour of the Dragon, also known as Conan the Conqueror. It centers on a middle-aged Conan, now king of Aquilonia, as his throne is threatened by conspirators who hope to depose him in favor of the kingdom's rightful heir by resurrecting Xaltotun, an ancient sorcerer from the empire of Acheron.

King Conan: Hour of the Dragon, which features covers by Gerald Parel and Sanjulian, debuts May 29.
