Tyrael was the one who cast the decisive vote from doris89592's blog

Even though Diablo IV Gold's character creation options aren't as extensive as those of other modern role-playing games, they can still be used to create great-looking, individualized characters while keeping the dark, medieval look that Blizzard is trying to achieve.

With a fresh look at Hell, Diablo 4 continues the story of Blizzard's popular previous games. The imprudences of man, holy messenger, and evil spirit lie at the core of the Diablo series, and the previous Lead celestial host Tyrael sits assistant in everything.

The council of archangels met to decide humanity's fate long after Inarius and Lilith secretly established Sanctuary for the Nephalem, the offspring of both man and angel.By tearing off his own wings and plummeting to Sanctuary, where the Nephalem's heirs live, Tyrael becomes the Fallen Star in Diablo 3.  

Tyrael was the one who cast the decisive vote; as a result, the rest of the Angiris Council would hold him accountable for that decision, resulting in his death prior to Diablo 4 for the sake of humanity. His job in the impending game is as of now hazy, however there are a few likely ways this critical figure could factor into the fate of the series.

Tyrael takes control of the Black Soulstone and banishes the Prime Evils with the help of a powerful descendant. Tyrael was the one who sent his companion to Pandemonium in order to Diablo 4 buy Gold eradicate death itself when Maltheal, the Archangel of Death, pursued the stone and turned against all of his allies.
