|Before Beryl became the commander of the Dark Kingdom, she was a sorceress from the Earth during the era of the Silver Millennium.
She hated the people of the Moon, as she had an unrequited love for Prince Endymion and hated Serenity for being his lover. Beryl was granted powers by the evil entity Queen Metalia, who had descended to Earth from the Sun when it detected the malice in her heart, hoping to use her to obtain the *Silver Crystal and conquer Earth. With these powers granted by Metalia, she managed to turn Endymion's subjects, including his Generals, against him.
After the war Beryl was reincarnated as a normal woman, while in the Arctic Circle, discovered the ruins of the Dark Kingdom and there reawakened Metalia - who returned her memories, then helped her to reawaken the Generals. They began to search for the *SC, in hopes that she could become the Queen of Earth with Endymion at her side.
