The Meat Mother was one of many gods enslaved by Gorr to build his Godbomb. These gods were eventually liberated by Thor, but many had been away so long that they no longer had any worshipers or could not remember where they had come from. Thor resettled many of these lost gods on worlds whose gods had been killed by Gorr.
The Meat Mother made her new home on Indigarr and, together with its other new gods, remade the broken world into a paradise. Far in the future, Thor’s granddaughters woke these new Sky Lords of Indigarr from an eons-long sleep to aid King Thor in his final battle with Gorr.
