In Avengers: Infinity War, Eitri says to Thor:
Three hundred dwarves lived on this ring. I thought if I did what he asked, they'd be safe. I made what he wanted: a device capable of harnessing the power of the stones. And he killed everyone anyway. All except me.
From the "on this ring" part, one might understand that he means there are more dwarves elsewhere. Is this correct, and if so, where do they live?
