Who was powerful enough to wake up a dead person, but it seems like he or she failed in their arts? If not, then he would be having a very hard time. Not like he was not having any, but it would have been tougher.

A royal princess on top of it.
She was none other than Znye little princess, Minya's baby sister.
Severus was scared with his own discovery.
He was not afraid of the dead corpse but the reason behind the corpse.
