El Indio Prison was a Confederate prison on Mar Sara for only the harshest criminals. It was considered to be underfunded and tough-as-nails, and had a 64 percent survival rate for inmates. Jim Raynor considered it to be the embodiment of Confederate justice, and prisoners feared going there.
The quickest way to reach it was to cross Perdition's Crossing, which was a dangerous lawless stretch of land. Jim Raynor was charged with transporting the convicts Marduke Saul, T-Bone Smalls, and Rodney Oseen to this facility, but after making a deal with his prisoners he arrived with only Smalls and Rodney, with Marduke earning his freedom by keeping to his word in fighting the Mazor gang.
