The Order of Vengeance is an ancient assassin's sect charged with the dutie of laying retribution upon the corrupt.
Living as rumor and myth to the general population, even other guilds know very little about this mysterious order.
Their reputation is shrouded in mystery and the simple fear of their retribution almost ensures steadfast vigilance against corruption among those who know they are real.
If ever enough blood is spilled the order's attention is drawn.
Many centuries ago The Imperial Warlords and the Legion of the Damned's incessant wars attracted that attention.
and so The Order of Vengeance traveled under countless pale moons to a land stricken with corruption and fear. Carpathia.

The idea behind The Order of Vengeance is based off of "The League of Shadows" seen in the movie "Batman begins" which existed injustice and corruption.
