Taln was bearded with dark brown eyes, and his Honorblade was narrow, long, and shaped like a spike. He was one of the more physically powerful characters introduced in the series.He had dark brown skin, like a Makabaki man.
|Obviously they are fools The Desolation needs no usher It can and will sit where it wishes and the signs are obvious that the spren anticipate it doing so soon The Ancient of Stones must finally begin to crack It is a wonder that upon his will rested the prosperity and peace of a world for over four millennia|
—— Pattern 1
After Aharietiam Talenel was left as the only Herald to keep up the Oathpact. In doing so he managed to suffer the horrors of his imprisonment for 4,500 years in order to keep the desolations at bay. His continued efforts in this way resulted in peace for mankind on Roshar for a long time in return for his own mental health. Although often considered to be simply insane by most it appears he has managed to keep enough sanity in order to warn others of the coming desolation, but not much more.He does not think the words but simply recite them off. At his introduction he still remembered who he was and his mission.
Taln is defined as "The man who thinks of himself as the Herald Taln, and whose viewpoint we got briefly in Words of Radiance." 
Herald of War
As the Herald of War it is likely that Taln was one of the more proficient generals and fighters of Roshar.He mentions to Dalinar and Elhokar that his role in preparing for the desolation would be to train their soldiers in the art of war.
Taln is one of the larger characters shown in the series, described as being at least as tall as Amaram while stooped over but far more massive to the point where he is likened to being built like a wall.His speed and reflexes are also amazing, as he was able to save Amaram from Iyatils assassination attempt purely by muscle memory and reflex while in an insane state of mind.
When he appears in Kholinar to warn of the coming Desolation he does this by cutting right through the city gates and then slamming them open, immediately after 4,500 years of torture, showing great endurance on his part.
He was also described as being a person who would continuously choose to take on seemingly impossible tasks and then give his life in realising them.
