Saal

Saal was a Sangheili Zealot of the Covenant Army. He was a member of Thel 'Vadamee's group that attacked UNSC ships at Charybdis IX during the Battle of Charybdis IX. The group was later ordered, personally by the High Prophet of Regret, to find the Kig-yar rebels that were trading Covenant weapons to Humans within the Rubble. Thel ordered Saal to brand himself with the Mark of Disobedience, a crisscrossing pattern made with an energy sword that envelops the forearms, after disobeying his orders not to torture the captured Jackal, Reth. Saal wished to kill himself instead, but Thel did not allow him to do it. Saal was promised by Thel that he could kill himself if he fought honorably, as is the Sangheili tradition. If he survived the battle, he presumably killed himself afterward.

He was also apparently extremely bloodthirsty, as noted by Thel aboard the Do You Feel Lucky?, "...looking for anything to kill."
