Agent Orango Seventeen is a character in Might and Magic Book One: The Secret of the Inner Sanctum. He is a "strange alien being in a shimmering silver jumpsuit", and can be found in the Soul Maze.
When the party is thrown into the Soul Maze, he tells them that to escape, they must find their captor's name "hidden within these walls". If viewed from above, the walls of the maze spell out "MY NAME IS SHELTEM".
The party must return to Orango Seventeen and tell him that Sheltem has imprisoned them. He states "Imposter XX21A7-3 voided!" and that "You are now Rank 1 and eligible for transfer. Find Inner Sanctum for new assignment."
The walls of the maze begin to fade, and the party members find themselves outside.
