[Marvel] Where did elder gods, like Galactus, originate?

I just finished the Annihilation Saga, and elder like Tenebrous of the Dark and Aegis of Sorrows. The chapter ending with them being "reclaimed" ??? What are the others of their kind?

Galactus was the last survivor of the previous universe, incubated in a cosmic egg. He was once a scientist, Galen, from a planet named Taa and happened to go exploring in space vessel with his chums when they were caught up in the universe ending.

It's unknown where Tenebrous of the Dark and Aegis of Sorrows originated, save that Galactus came before them and they have some relation to him. Except none of his companions survived.
