The legendary Tablet of Death and Entropy is the long-lost counterpart to the Tablet of Life and Time. Apocalypse discovered that it could reach across the veil between the living and the dead, carrying messages from the afterlife — even from Mistress Death herself. In his Collapsed Timeline, a single syllable of her whispers was enough to drive mortal empires to embrace their own destruction. That is why Apocalypse sealed the tablet within his own body, where it remained until the Hood seized it amid the chaos in Thebes. Perhaps he carried it not to wield its power, but to keep it from snuffing out the very will to survive.
