Stars and Glitches (Erratum x Rosalina)

There are 2 Entities that suffered from sadness.

One of them left her homeworld to the Cosmos out of curiosity, the other in where he left his realm out of being captured through experimenting on himself.

One where she became a mother of stars by her own will, the other where he was forced and corrupted in becoming a destroyer by another deity.

One where she had been given the simple, happy life of being the adoptive mother to the stars, the other who sadly struggles to be a father to his spawns in the middle of a very harsh catastrophe.

One where she continues to live, even where she has past the limit of her age, and remained youthful, and the other where he had been cursed with immortality, and he had died once, before having gained immense power in return.

So what happens, when one of them simply has enough, and takes himself, and his children to the void, only to end up where the mother of stars resides in, and more importantly of all, how will she help the destroyer and his children with the suffering that they had went through for a very long time?
