If Hell is forever then Heaven must be a lie - Arc I: Pestilence

A week has passed since the angels were forced to retreat and the Extermination was cancelled; the Hazbin Hotel has been rebuilt, peace reigns again, and although the demons still seem reluctant to embark on the path of redemption Charlie is optimistic about the future. That is, at least until an unexpected guest shows up at her door asking for help, revealing the first of a long series of secrets that Heaven and Hell have kept for centuries. With the discovery that redemption is possible, the return of an enemy who was thought to be defeated, the emergence of new threats, Hell which increasingly descends into chaos where the most evil are the masters, and more and more hidden truths that come to light, what will happen to the Hazbin Hotel? Will Charlie and her friends be able to at least save themselves, or will they be consumed by the anarchy into which the entire cosmos is slowly sinking?
