Mecrosa Order

The Mecrosa Order was originally the group of protectors of the Tapani Sector's noble House Mecetti. Formed around 4,200 BBY on the planet Nyssa, their primary goal was to prevent outsiders from attacking the House.

Around 4,000 BBY, Viscountess Mireya of Vjun was married into the House, bringing with her Sith teachings. From Mireya, the Order was turned into a Sith cult of assassins that produced a number of Sith Lords, fighting for Exar Kun during the Great Sith War.

The order was nearly wiped out by the Jedi Knights, aided by House Pelagia, during the Cleansing of the Nine Houses. However, members (both Force-sensitive and not) survived until at least the New Sith Wars, where they were allied with the New Sith Empire. Around 1,230 BBY, in an act of treachery, they poisoned the Dark Lord of the Sith Belia Darzu for her unwanted incursions into Tapani Sector space.

Under the rule of the Galactic Empire, young Mecetti nobles revived the Order. During the Great Jedi Purge, the Order's top agent, Sir Nevil Tritum, retrieved the Sith holocron of the ancient Sith Lord Adas from House Pelagia. Following the Battle of Endor, the Order gave the holocron to Lumiya.
