The Heresiarchs were a cult derived from Sith lore and teachings, known for its deterministic philosophy. Emperor Palpatine had mastered and gone beyond the recovered teachings of the Heresiarchs long before his return in 11 ABY.
Behind the scenesEdit
A heresiarch is a founder or leader of a heretical doctrine or movement (cult), as considered by those who claim to maintain an orthodox religious tradition or doctrine. It is possible that 'Heresiarchs' is an abstract term for unorthodox dark siders or simply their leaders, rather than a certain movement.
