An achievement relates to a 'bone xylophone' and dancing dead, a nod to an event in KQ6. While original King's Quest lore had more than one 'afterlife' where spirits could travel too, ruled by the diety Azriel or the trapped and undead human Samhain. In the reboot universe it seems that all spirits end up in the Land of the Dead. From there they end up continuing an existence inside areas representing their former places of work.
