Sebiascor Ebongrave

Lord Commander Sebiascor Ebongrave is the present day leader of the Canis Salient of the Achilus Crusade.

Ebongrave was a capable, even heroic officer who distinguished himself among the cavalry of the Dhkasin Hussars and became a trusted advisor to then Warmaster Solomon Tetrarchus before being given command of the Canis Sailent.

The Lord Commander has not borne his role well. This once dashing cavalryman is a bitter, graying man who rarely leaves his fortified situation rooms in the Achilian Bastion. He has become increasingly paranoid and has ordered purges of regimental commanders, naval officer classes and Imperial governors, sometimes at the vaguest suggestion of T'au sympathies or ideological weakness.

No matter how impossible the fight against the Tyranids of Hive Fleet Dagon becomes, he refuses to countenance diverting troops and ships from fighting the T'au. Some believe he is losing his grip on reality, while others think he sees reality all too well and is the only man who appreciates just how devious his xenos foes really are.
