Caïus Ignatius Juvii

First Defender Caïus Ignatius Juvii] is a notable Primaris Space Marine of the Mourning Wardens Space Marine Chapter and the first to rise to the esteemed rank of First Defender.

Background
Juvii is the first Primaris to rise to the rank of Defender, and then First Defender. His glory came shortly after the terrible Siege of Catovar, when the Wardens petitioned the great Guilliman for Primaris recruits. Caïus was among those dispatched to help the young Chapter. He proved to be a strategic mind of the utmost caliber, and a great warrior to boot. Able to work seamlessly with both his Primaris brethren and his normal Astartes Brothers, his rise through the ranks was meteoric, but always too slow for his taste.

Since he was promoted to First Defender, Juvii has spent most of his time waging war against the enemies of the Imperium, besieging Traitors' bastion, defending crucial worlds from the teeming horde of xenos and proving his mettle and abilities. His talent is such that many already assume that he'll become High Protector when Singla will be killed or entombed into a Dreadnought. Some, however, dislike the arrogant nature of the Primaris, keen to remind his Brothers that he was born on Terra itself when the Emperor still walked. This one flaw could be his undoing, should another contestant rise through the ranks of the Mourning Wardens.
