From Ivyscan:

Having been born with an ability to destroy things without having to touch them, a man was abandoned by his mother when he was a child. His name long forgotten, he continues to travel aimlessly, crossing paths with those with superhuman powers along the way. These encounters are perhaps brought about by his own power.

Follows the rather tempestuous relationship of two writers and touches on the lives of those they interact with. Both those that hate and/or envy them and those that love and/or like them. Not a modern story, it seems to be set at least several decades ago, before computers at least. Despite this, it doesn't have a dusty, out-of-date feel to it, more like a slow-tempo modern story.
