Oh, I can answer that now.

Much like the title Heaven's Quintuplet, The Progeny of Destruction is basically just like that.

The Quintuplets are babies abandoned on an island. They were given relics of great power that took care of them since birth, teaching them everything they needed to know and moulding them into great beings that could make use of the their powers. All of them gained Immortality due to continuous exposure to otherworldly energies but due to the energies being different their type of Immortality is different.

Heaven created the relic given to Heaven's Quintuplet thus he was named that.

Destruction created the relic given to the Progeny of Destruction thus he was named that.

They were trained by the very spirits created by these Entities and thus was titled after them
