Grayl was female Human slave, orginally owned by Orge Ralth. After she saved her master from assassins, Grayl was became Ralth's plain-clothes bodyguard. Likewise she was rewarded with treatment that exeded that of any other slave. Some scornfully said that Orge treated her more like his daughter. When Orge died she was passed onto Fodor the Hutt. She would remain the personal slave and guard of every Overlord of the Underworld, up until Mandy Jaal. Under Fodor and Pretentieux Grayl acted as a dancer, but kept a concealed weapon which she could deploy if needed. However, Muggera had distrust for all Humans, particualarly slaves. Therefore she was reassigned as an average dancer again. But Mandy, being female, had no need for exotic dancers and therefore, Grayl became her decoy and impersonator. She was impersonating her mistress when Imperial assassins killed her.
