The Sky Lords of Indigarr were Gods on their planet until stories about them started fading away, along with people's beliefs in them. For centuries the Sky Lords did not appear to their people until one day Thor went to investigate how there can exist a Godless land. On arriving at the Sky Lords' city, Thor uncovered they had all been butchered to death.
The Sky Lords of Indigarr were created by writer Jason Aaron and artist Esad Ribic. They first appeared in 2012 story "The God Butcher, Part One".
