His role in the new game is unclear at present from buryw's blog

Then, long after Inarius and Lilith had secretly created Sanctuary for the Nephalem - - the result of both angels and Diablo 4 Gold men - the Council of Archangels came together to decide the world's fate. Tyrael was the one who cast the final vote, and consequently, he was held accountable by other members of the Angiris Council, leading to him dying prior to the events of Diablo 4 all for the for the sake of humanity. His role in the new game is unclear at present, but there are some likely ways this pivotal figure will be considered in the future of the series.

Diablo 3 gets deep into Tyrael's story, as he turns into"the Fallen Star by tearing off his own wings before falling to Sanctuary where the descendants of the Nephalem live. By joining forces with a powerful descendant, Tyrael defeats the Primitive Evils and gains the control of the Black Soulstone. If the Archangel of Death, Maltheal, went after the stone and took on all of his followers Tyrael was the one to brought his partner to Pandemonium to destroy death itself.

Tyrael opts to stay in his mortal form . However, he joins his angelic brethren to transform into an Aspect of Justice as well as of Wisdom. Diablo 3 ends with him contemplating whether his new mortal counterpart, who could be corrupted, should soon become the next challenge of Heaven, Hell, and Sanctuary or even the life itself. There's a reason that Aspect of Justice and Wisdom likely won't sit idly by while Inarius marches an army upon Hell in search of his former love, Lilith.

The latest Diablo 4 cinematic trailer from Blizzard includes Inarius in a battle against Lilith Armed forces at both of their backs. Although the scene doesn't show Tyrael's personal involvement, his design of the Horadrim and influence with the various Paladins of Sanctuary indicates that he's involved. Dark and light clash on the battlefield, while the now-mortal Tyrael lies somewhere between.

It is highly likely that his presence will be felt through these intermediaries until events cause him to act. Tyrael is still feeling the repercussions of the destruction of his Worldstone at the end in buy Diablo 4 Gold.
