You don't need spoilers!!!

This story explains everything that happened in the twins past.

When Gramorr was "defeated" Mephisto sacrificed himself to save him sister. He died from the blast. Or did he? This is Mephisto's story.

Is there more to Mephisto and Praxima that meets the eyes? Is Mephisto taking all the hits for the failed missions? What if Gramorr came up with not one, but two foolproof schemes to destroy the Princesses? Would one of the twins change? (I do not own the characters.) (This is only about season1, so Mephisto hasn't been blasted ?)
