The missing Endless is Destruction, the fourth eldest sibling of the Endless, after Destiny, Death, and Dream.
Destruction abandoned his role as an Endless and his responsibilities, choosing to leave the realm of the Endless to live a more mundane existence. He is described as having a "dark and destructive" nature, which he embraced as his own, but ultimately decided to leave behind.
This decision led to his absence from the Endless family and from the role he had once played in the universe. His absence has had a significant impact on the balance of power in the universe, and it is unclear whether he will ever return to his role as an Endless.
