Earl Rambert is an Erathian Earl appearing in Revolt of the Beastmasters, the seventh part of Heroes Chronicles. When Tarnum had slain Lord Onsten and Baron Paglon on his quest to free the Mudlanders from Erathian slavery, he then moved into the lands of Earl Rambert. Mad King Gryphonheart, eager to end the rebellion, sent his son Prince Niven to aid the Earl. While Rambert appreciated Niven's tactical genius, he found the prince to be far too soft with his prisoners, and when Niven managed to capture a group of Mudlander noncombatants, including Adamina and the other wise women, he begged the prince to execute them, but the prince refused.
