Neyrelle is a character in the Diablo IV universe who plays a significant role in the "Vessel of Hatred" expansion. She is an adventurer and a scholar versed in Horadric arts2. In the expansion, Neyrelle is tormented by the malicious wills of her traveling companion, Mephisto, one of the Prime Evils.
The challenges Neyrelle faces in the "Vessel of Hatred" expansion are primarily related to her struggle with the powerful and corrupting influence of Mephisto, who is trapped within a soulstone that she carries1. As she journeys through the jungles of Nahantu, she must navigate the dangers of the region while also resisting the dark plot that Mephisto is attempting to enact.
Players will embark on a quest to unravel Mephisto's plans and save Neyrelle's soul, all while facing new foes and challenges presented by the expansion's storyline and gameplay additions.

The "Vessel of Hatred" expansion introduces a new class called the Spiritborn. This class is an entirely new addition to the Diablo series and is ranked among the apex predators of the jungle. The Spiritborn is battle-hardened with mystical synergies that could only be awakened deep within the jungles of Nahantu. They embrace the ethereal Spirits entwined with this ancient civilization. While specific details about the Spiritborn class remain shrouded in mystery, it is known that they possess unique abilities and battle tactics that have not been seen in the series before.
