Mablung the Unrelenting

Mablung the Unrelenting is one of the greatest Heroes of the Ashen Thanes chapter. He is also the oldest marine of the chapter, being interred in an ancient Contemptor Dreadnought. Before his internment in the dreadnought he was the only Astartes of the, then Iron-Bound Thanes, to receive the title 'Ar Huan" or 'Great Hunter'.

History
Like most of the chapters early history most of his early life was lost when the World Burning happened. What little now remains comes from his own recollection. Even before becoming an Astartes he was a skilled hunter, living outside the warring kingdoms. It was only through rumor of his skill that the Iron-Bound Thanes heard tales of this young boy who could hunt better than a grown man. Eventually, deep in one of the planets Great Forests the chapter's recruiters found him. Seeing in him great potenital he was invited to undergo the trials of the chapter, he accepted. Seeing he was already a masterful hunter he was allowed to skip the first trial and proceed directly to the second trial. While he passed the 2ndtrial with flying colors he nearly failed the 3rd, only passing because his partner surrendered to him out of respect and Mablung would not fight because he viewed fighting a foe who already surrendered to be dishonorable.

As an Astartes
Once he began the process of becoming an Astartes of the Emperor he like all neophytes became a scout marine. There he excelled, having learned all about silent movement and killing in his youth. First of his Battle-brothers he was promoted to Devastator marine, then Tactical with record speed. Wherever he was put he showed skill beyond his peers and many expected him to get the honor of joining the Deathwatch. However he never got the chance as his officers saw in him a pair of deadly flaws; he often lost sight of his mission to pursue enemy champions and commanders and, strangely for the chapter, he worked alone. Having grown up in isolation he worked best when not around his battle-brothers seeing them as an impediment to tracking his foes at times. Rather than discipline him for these callous feelings the Chapter Master decided to appoint him a unique honor. to become the chapters first Ar Huan (Great Hunter). Working outside the companies he would work alongside them under the direct command of the Chapter Master to hunt the most elusive of their foes.
