Akin to 'Set' from Old Earth mythology, the antithesis of Osiris was meant to be the balance to their counter-part's Dominion.

The Enclave of Setesh in modern Sirius, are an extreme and contradictory split to the more traditional trans-Sirius order, focused on the complete annihilation of Outcast society due to their unique and at times dangerous tendencies, along with all those connected to them, even remotely.

Inquisitors of the Enclave operate without any true sense of morality, seeing a full-scale extermination as the only means to restore man-kind's supremacy and to finally bring about an age of prosperity in Sirius. To these Inquisitors, there is no cost too great and no number too large for sacrifice. Inherently selfish, fanatical and unpredictable, are seemingly the core of those few who constitute this cell's ranks.

Crude methods and sheer brutality are major parts of the cell's modus operandi, being specialists in shock and terror tactics and making do with limited numbers and limited resources, choosing to field light ships over capital assets, with no restrictions on how to eliminate a source of the plague.

Indoctrinated and brainwashed to be purifiers of this taint by their former Masters, these formerly dutiful servants will not let their sacrifices be in vain and will almost religiously continue what they still see as their duty. For they know nothing else.
