The Acolyte's Sith Lord: All The Clues That Make Us Think We Know Who He Is

[هَـ-ђāŵĩ-ـَاوِيتم التحقق من هَـ-ђāŵĩ-ـَاوِي كعضو.]

The Acolyte features a mysterious new Sith Lord, and here are all the clues to his true identity. Officially referred to only as "The Master," The Acolyte's Sith Lord is clearly a force to be reckoned with. He made his proper debut at the end of The Acolyte episode 4, generating a telekinetic blast that tossed Jedi around as though they were flies caught in a hurricane. Like many Sith Lords, he wears a mask; this has led viewers to speculate he's concealing his true identity, and that he's actually someone else in the show.
