Nerevarine cult

This is an ashlander cult. They believe they nerevarine will be reborn to honor ancient promises to the tribes. Will be cast down by the false gods of the tribunal temple, restore traditional ancestor worship practised by the ashlanders and drive all outlanders from morrowind. Both temple and empire outlaw the cult but it persists among the ashlanders who don't care about the imperial or temple law.

Prosecuted by the temple and since the cult is hostile to the empire the empire doesn't intervene.
