Osiris' sword didn't intend to kill her. Instead, the sword only intended to destroy the bindings that were keeping her trapped.
Without the Moral Shackles of being the King, Osiris couldn't come to let him leave Yulia behind to die in this place.
"Get inside the Tower!" He commanded her.
Lia was momentarily stunned to see Osiris free her. She couldn't believe her own eyes even though she was seeing it take place right before her.
Seeing her in a daze, Osiris held her hand and started bringing her back to the tower as the apocalypse became even worse for her.
" This can't be real," Yulia's spirit watched what was happening right before her eyes, unable to believe it. This went against all her assumptions.
"This is as real as it can get," the old man answered. "This is how the real events took place. Surprised?"
The old man had expected a similar reaction from Yulia, so he wasn't much surprised. The reality was often more surprising than legends and myths.
