The Lunatic

Anglor is a Selenite, a creature from the moon, with a divine mission to rescue Earth, against his will, a reluctant supposed messiah. But he has many different customs and ways he thinks that are different from earthlings, so Earthlings write him off as insane. Under the alias "Michael Smith," Anglor becomes an artist with a mission, to "kill history," but it doesn't quite turn out the way he wants, him being on an impossible mission from the stars, to save a world he is not only not from, but which he doesn't belong in, being The Lunatic.
