Hephaestion

The Servant, who appears in Lord El-Melloi II-sei no Jikenbo. Her Class is unknown.

She is a Faker, Heroic Spirit of Imitation, an Extra Servant Class created by Doctor Heartless

Faker's True Name is Iskandar's Shadow. She was the younger twin sister of Hephaestion, one of the generals serving under Alexander the Great. She was taught from a young age by Olympias, Iskandar's mother, to act as a body-double and confidant to Iskandar, and also acted for her brother at times. For this purpose, she was never given a name, and borrowed her brother's when needed. Combined with spreading rumors of Iskandar's appearance as based on her own, so distinctly different from his, she was the ideal vessel to receive any curses directed towards Iskandar.
