Jumping in the train that Hob is the anthropomorphic personification of Hope.
But instead of being formed/born as Hope, he ascended in that position. He earned the position.
And not just Hope, he can also be Humanity or Change.
His duties were done by simply being him. Continuing to love life, continuing to change for the better, and helping those that are in need. A simple smile can change someone's day, and a simple talk can change someone's life for the better.
Unlike the old/ original Endless, he doesn't have a realm; his so-called kingdom is the waking world.
Another thing is that once he stepped into the dreaming, everyone that is dreaming at that moment dreams of nothing but hope and love.
He only finds out about his ascension when Desire kidnaps Hob and puts him in hell, but when Dream rescues Hob, said personification of Hope is already out of the gates and has a permanent ban on the place. Hob didn't say anything to his friend.
He lied, almost causing a fight between them. But Dream finds out not a day later when Desire tries, keyword tries, to kill Hob. The Kindly ones appear, giving a warning to not to harm the newly ascended Endless. But immediately stating that Hob is not their sibling or relative, winking at Dream's direction.
