Even as a mortal there was something unwholesome about the Tainted, some uneasy aura that lead men of good heart to shun him. He endured through the protection of rank and virtue of high birth, but sank deeper into depravity with each passing day. it was simple task for Sauron to ensnare this fallen Man, to feed and nurture the sparks of corruption until they rampaged through his body like wildfire. Where other Nazgul were slowly swallowed by the taint of their rings, the Tainted gave himself wholly and willingly to Sauron. Now all natural things rebel in his presence, vegetation withers, animals sicken and bold warriors cower. he is an abomination whose merest presence is poison to life, honour and hope.
