Battlemaster Halak Rinn was a krogan battlemaster of the Krogan Halak Clan and son of clan leader, Halak Marr during the Krogan Rebellions. Born on Tuchanka Rinn was cocky and headstrong always believing that brute force was the best alternative. Always favoring fighting over negations. This earned him great respect among his clan-mates who favored his strength and refusal to surrender. It also earned him disdain from his father who believed he was being stupid for not accepting help. Despite this he was still given a seat on the Krogan Union. And was one of the krogan targeted by Turian Spectre, Salck Mullen.
