But it was one fateful day that really put him on his path. He and a team of Marines had actually succeeded in subduing a Brute-led siege of their ship as they traversed for the first time into Covenant space. They managed to tranq the six Brutes who boarded, but they should have killed them. When he got a really close look at them he was in awe. But the tranq darts wore off fast on these behemoths and their attempts to contain them quickly proved feeble. The pack literally tore their way out of the synthetic alloy constraints.-Chpt.3 pg 60
