Trivia Pela is a member of Serval's rock 'n' roll band.[1] The back of Pela's phone case shows characters from Tears of Themis. Etymology The name Pelageya derives from the Ancient Greek πέλαγος pélagos, meaning "of the sea, marine." Pela's "last name" — Sergeyevna — is not actually a last name. It is a patronymic meaning "daughter of Sergey."
