Decimatus

Decimatus was a  who lead the Brute and Covenant Remnant defenders of the Jiralhanae colony Ferinus, a remote, continental world on the outskirts of Brute-held territory. Decimatus was widely feared, but barely respected by the various ground troops that he commanded. He was infamously known for mistreating his own pack, often making brash tactical decisions stereotypical of Jiralhanae.

Decimatus was killed by the -class Fleet Master Stel 'Vadam, ending the Ferinus Campaign.
