Erbrad de Castelrous

Erbrad de Castelrous was a notable legend of the Mourning Wardens Space Marine Chapter, but whose name is now attached to infamy and failure, providing a cautionary tale to his fellow battle-brother of the hubris of pride.

Background
Erbrad de Castelrous is a legend in his Chapter, but alas one which is deeply intertwined with infamy. A simple Battle-Brother among the firsts to be inducted into the Chapter, Erbrad displayed an incredible drive to succeed. He always held himself to the highest standard and from simple soldier to Sergeant, and then Defender, he expected that his warriors would match his zeal. It is this drive which allowed him to ascend to the rank of First Defender. But once he had reached such height of honour and power, he grew complacent.

This weakness doomed his Company on Catovar. This planet was plagued by mysterious raiders before the Cicatrix Maledictum formed, but when the great scar in reality opened, a Chaos pirate fleet attacked this world. Erbrad led the defense, but he was completely unprepared by the viciousness of his opponents, nor their tactical advantage. The Mourning Wardens only barely held their ground, and the Siege of Catovar was only breached by the rest of the Chapter's intervention, and the help of mysterious Drukhari.

After the war, Erbrad was demoted to the rank of 9th Defender, Singla refusing to let his potential go entirely to waste. However, his failures weigh heavily on de Castelrous, whose spirits seems to be broken. So far, he has shown no interest to shake off the infamy associated with his name, even almost a century after his greatest shame. Still, the amber of greatness still smoulder in the Astartes' hearts and in recent months, the information that the very same Dark Eldar who appeared on Catovar, re-appeared to raid territories near the Chapter's homeworld has piqued his interests.
