[Supernatural resurgence + wild imagination + bizarre tales + death games + battles of wits]
After that great flood,
Some people disappeared, while others appeared.
Some people were no longer human, while others had never been human at all.
Those who remained struggled to disguise themselves. Society carried on as usual. Ghosts had to follow the rules, and the strange species had to maintain order. Until the fated hour arrived, when everything would draw back the curtain on the end.
