He is the eldest of the Endless, and is portrayed as a tall figure, obscured within a brown robe and cowl. He reads what is to be from a the large book chained to his right wrist. He does not leave footprints, nor does he cast a shadow. Destiny's realm is a garden, the maze-like paths of which he walks continually. His book is his sigil in the galleries of the other Endless.
He is the least characterised and least used of the Endless in the series. He appears first at the beginning of the fourth collection, Season of Mists. In a quiet way he seems to direct Endless family affairs; it is he who calls the family meeting that begins Season of Mists.
