One of the more interesting comics I’ve been reading via Comixology is Last Days of an Immortal. It deals with a number of alien races that all have different values, ways of communicating, laws and physical forms.
In the distant future, Elijah is a member of the “Philosophical Police,” who must solve conflicts that arise out of ignorance of the Other. Two species are fighting a war with roots in a crime committed centuries ago, and Elijah must solve the crime and bring peace between their species, while also confronting his own immortality in a world where science provides access to eternal life. In a world where death no longer exists, why do so many want to give up on life?
