Most angels live in heaven and are in their true forms which are energy entities the size of a skyscraper. Unless the leviathans are as big as angels and they can enter heaven, which I doubt, Death meant they would devour physical creatures around the known universe. on planets. Archangels live with God or at least right next to the proximity of him.

The 4 archangel brothers and Death the Horseman are the only ones who've seen God's true image. They converse and even have a relationship with him. It's perfectly logical and within reason that they should be older than Dick, Edger, and the rest of the leviathans.
