The Blind Legion is a Cabal unit on Mars deployed as specialists in recovery, demolition, and extraction operations. They are the smallest Cabal Legion on Mars, but they are the most experienced, and the best trained.[citation needed] They are constantly engaging the Vex, particularly over Vex artifacts recovered by the Cabal, either defending them or stealing them.[citation needed] The Blind Legion is the Cabal's scalpel of a unit: precise, deadly, and efficient.
