スフィンクス

A mixed beast monster that guards the Pyramid, believed to be older than 1,000 years old. Through her long life, she has come to wield powerful magic. Through various circumstances, she has become the judge over the [Dragon Seal Trial]; however, it seems she despairs at her role and lives her life in immersed hopelessness. Those who fail the trial are violently raped, then eaten. She forces her prey to be entranced by pleasure as she swallows them whole and slowly digests them inside her gigantic stomach. Her enormous magic, built up over hundreds of years, renders her all but immune to any type of sealing magic. [From In-game Monsterpedia]
