Mass Effect 2 & Mass Effect 3
Founded by notorious batarian slaver Solem Dal'serah, the Blue Suns began as a Skyllian Verge protection racket providing genuine protection from slavers and pirates. Eventually captured by the Systems Alliance Navy, Sal'serah beat almost two dozen charges to be convicted on a single count of conspiracy. The slaver benefited from the tutelage of cellmate and brilliant con artist Bernard "Legits" Ledger. Upon release five years later, Dal'serah incorporated Blue Suns as a legal security agency.
Today, the Blue Suns boast a galaxy-wide force of batarians, turians, humans, and krogan. Each deployment is backed by a logistics corp selling everything from heavy weapons to shaving cream. Despite claims that Blue Suns sells its captives as slaves, no Blue Suns employee has ever been convicted on such charges.
Many Blue Suns members sport the company logo in tattoo form, removing during assignment and reapplied at mission-end.
