Did it sound foolish to attempt to assassinate an undying Undead Emperor? In this world, however, there was no such thing as truly undying.
Even the True Gods, who called themselves eternal, could perish. So-called immortal liches would naturally die if their phylacteries were crushed. "Undying" individuals were only undying because the correct method to kill them hadn't yet been discovered.
Killing an undying individual with the wrong method would force that individual into a temporary hibernation. For example, it would take liches and high-level Blood Tribe members about two or three years to recover their strength and come back for revenge.
Some things were common for all the undying. For instance, one would greatly weaken when they lose their physical body, making it impossible for them to run amok for a while.
