Muerte's Escape into the realm (This is what he was doing for the last several years.

Chad wanders around the land feeling that several things have gone wrong with his return to the palace, when he deiced to do one thing, he abandoned his throne to find what remains of the powerful kings that came before him. This hollow world of Hueco Mundo had several thousand years of history because time moves some what faster here it has around 1000 more years then the human realm, he learned that many human religions have demons and seeing where most hollows make their debut is in Japan we are most likely yokai. On his travels he gained power of the old kings had several fights with hollows on the level of vasto lordes devouring them to survive with food. His body becomes scared and with bite marks, claw marks, and burns. He keeps the shard of Kira's mask around his neck so he can keep his sanity. Eventually however, he loses this mask shard and gave up his powers as a soul reaper to gain the truth from a man who was once looked upon as a god. In the tomb of Azien he saw things that didn't make sense coming from the mouth of the one who became both hollow and reaper, one of the inscriptions said, 'One must kill ones self to truely become powerful.' So he killed off the side that caused him to leave the throne, his mistake of being a soul reaper. After that he found the hollow who stole the shard and mascaraed him and his "friends" because nobody, but a king has friends. As his power grows his hair starts to grow out down to his waist. After several years later he walks to the palace, not knowing what he would find. He finds his brothers and sends them out to find the other seven espada to bring them back to the palace. But before they left they let go of their soul reaper powers to become pure hollow. Before they left to search for them they murdered Zero, but not Daisake because Chad could not and would not let them kill the kid who understood him the most. All the espada was found and brought before the king and there was a new espada 0. Chad looks at the moon often in this story waiting Kira and waiting for her to return all the while looking at the mask shard in his hand.
