In brief
Blizzard's next Diablo hands you a hero who is tied to the Lord of Terror himself, and nobody will say why yet. The Heir of Westmarch is built around a two-way link with Diablo: you get insight into him, and he gets a way into you. Originally reported by TechRadar.
Meet the Heir of Westmarch

Diablo 5 drops the Wanderer archetype. You play the Heir of Westmarch, a fugitive running from the forces of hell.
A bond with Diablo

Narrative director Jennifer Hepler says the Heir has a link to Diablo himself, and the game slowly reveals how it formed.
“a unique bond with Diablo that you find out over the course of the game, why and how it came to be”
Insight cuts both ways
That bond gives you a read on the Lord of Terror. It also leaves you open to him in a way nobody else is.
“insight into him, but also a unique vulnerability to what he can do to you”
Resist him or use him

Hepler frames the whole game as a question of whether you hold the line or turn Diablo's power back on him. Story and combat both answer it.
“Can you resist his influence? Can you turn his powers against him?”
Surviving the terror realm

The plot proper kicks off when the Heir walks into the terror realm and comes back out alive.
“the story really begins when you find out that you can enter the terror realm and survive”
Spring 2029 is the wait
All of this came from the Forging the Next Era panel. The release window is Spring 2029, so details will trickle out for years.
In short
The Heir of Westmarch is built around a two-way link with Diablo: you get insight into him, and he gets a way into you.
