At the beginning of "Harry Potter and the Deathly Hallows," Lord Voldemort kills Severus Snape, mistakenly thinking it will make him the master of the Elder Wand. Snape's death unveils crucial information, shaping the narrative and impacting the ultimate defeat of Voldemort.
In the beginning of "Harry Potter and the Deathly Hallows," Lord Voldemort kills Severus Snape. This act is part of a larger plan, as Voldemort believes that by killing Snape, he will become the true master of the Elder Wand, one of the Deathly Hallows.
The Elder Wand's allegiance is won through acts of killing, and Voldemort believes that Snape's murder will transfer the wand's allegiance to him. However, this understanding is flawed. Snape's death is a critical moment in the narrative, revealing his loyalty to Harry Potter.
Before dying, Snape passes on crucial information to Harry, contributing significantly to the unfolding events and the ultimate defeat of Voldemort. Snape's death sets the tone for the darker and more intense themes explored in the final installment of the series.
