Lamo shook his head: "He's in the grave and cannot be resurrected. Lord Durken said that if he were to be resurrected, it would consume a lot of soul energy. This is a closed space, and with the consumption, a lot of souls would perish. So, he decided not to resurrect himself. He asked us to wake him up if we can get out."
Negris nodded. He might not have understood this before, but ever since Ange brought in the Liquid of Breath of Death into the Resting Palace, allowing it to freely evaporate, the level of death breath in the Resting Palace has reached saturation.
Since then, Negris realized that death breath was as vital to the undead as air to the living. Without it, the souls of the undead would wither.
If Lord Durken were to be resurrected, it would consume the limited death breath in here, and the remaining souls would wither and gradually perish due to the lack of nourishment from the breath.
However, now that Ange is here, Lord Durken is saved.
