Legion

Interesting.  Use for an NPC? 

Mark 5

¹ And they came over unto the other side of the sea, into the country of the Gadarenes. ² And when he was come out of the ship, immediately there met him out of the tombs a man with an unclean spirit, ³ Who had his dwelling among the tombs; and no man could bind him, no, not with chains: ⁴ Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him. ⁵ And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones. ⁶ But when he saw Jesus afar off, he ran and worshipped him, ⁷ And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not. ⁸ For he said unto him, Come out of the man, thou unclean spirit. ⁹ And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. ¹⁰

Update:  Refer not to any one NPC, but the residents of the Empire?  "Legion" seems to fit.
