Undeath is a concept Rot began long ago with her necromancy cults but Misery decided to act on after Evil's stay as "Misery" - with lots of death being introduced to Misery's realms she began to get more militant on her goal of stopping the "Life, Death, Rebirth" cycle.

Many souls formerly trapped in Misery Zones, thanks to Evil, will die and / or become annexed into the Depths of Depravity - which means Misery loses a lot of her former influence.. Undeath is part of her quest to regain lost territory and claw her way back to power.
