The conflict with Zanth did not resolve itself with the destruction of The Heart of Despair; a single ball of light suddenly decended upon the area where the heroes all landed: The Parish District.
The ghosts were back. All of them. And they were saying the same things as before. White Flame approuched the ball of light. "How?" Zanth's voice suddenly spoke out. "How are you able to ignore the voices?"
"What voices?" White Flame asked. "I can't hear any voices. Not anymore. Simply because I choose not to hear them."
"I...I don't understand...how can you forget? How can you forgive?" Zanth asked.
"The despair is over Zanth. If you will it, you can choose not to hear the voices too. And then, you can be reborn." White Flame said.
"Would...anyone really forgive me? After everything I've done, everyone I've killed...would anyone truely forgive me?" Zanth said.
"There is one person who forgives you Zanth: Me. I forgive you." White Flame said before suddenly he touched the ball of light.
Suddenly, the ball of light morphed into a white unicorn colt about White Flame's age; in fact, outside of the color and the cutie mark of a black heart, the colt was like White Flame's identical Twin brother. The colt's eyes were closed as the ball of light gave form to this colt, and when it was gone and the colt was gently lowered to the ground, the colt began to awaken...
As the colt finally woke up, they looked over themselves as if they weren't used to themselves, and then stopped to look at their hooves, before tears began to well up in their eyes.
"...H-hooves...I have hooves..." The new colt said; their voice identical to Zanth's voice without the strange garble behind it. It sounded like a carbon copy of White Flame's voice. "But...but more then that...I have a body...I have an actual body." The colt said. He then began to cry obsessively.
"I'M NOT WORTHY!"
Was the phrase he cried out in pure and utter joy.
It took some time, but the colt formally known as Zanth finally ceased his tears.
"...I've heard that if you seek forgiveness, you must first forgive youself. But I doubt the phrase has anything on this." Starswirl the Bearded said.
"I...I really don't deserve this. I...I just..." Formally Zanth said.
"It may take forever to atone for the damage you caused. But if I can live a normal life. Then, you can too...Black Heart." White Flame said.
"...Black Heart...that's my new name then...I see...I understand..." Formally Zanth now Black Heart said. "I guess...I don't care how long it takes: I will atone for everything I've ever done when I was Zanth. Just like you have, White Flame."
"I know you will. You've already got friends here who can help you push past the despair, and really, truely, start living instead of just being." White Flame said.
"Yeah, I think we can both work on that path of self-improvement." Diamond Tiara said, putting an arm around Black Heart.
"When'd they get here?" Twilight asked.
"We saw the light, same as you. Now, I think there's a double wedding to enjoy." Diamond Tiara said. "After the Heart of Despair basically went cuckoo crazy, the storm king's forces just...surrendered. Most are being let off easy, but the enforcer of the Storm King asked to speak to Princess Twilight specifically."
"...Huh. Wonder why that is? I best not keep her waiting." Twilight said.
Twilight then met with Tempest Shadow; or rather, Fizzlepop Berrytwist. With some help from Twilight, the Unicorn was able to have a magic horn now. It wasn't a real horn, but for the first time since childhood, Fizzlepop felt whole again.
Applejack meanwhile, did not look pleased at the fact that Zanth was basically being given a get out of jail free card. The colt formally known as Zanth soon came up to her. "You may be able to gain every pony else's trust; but it's going to take a miracle before ah can even begin to trust the likes of you." Applejack said.
"I had a feeling you might say that." Black Heart said, before he tilted his head to look past Applejack. "Which is why...I think there's two ponies you should meet, that with my advanced magic, I was able to rescue, and find for you." He said.
Applejack had a confused look on her face, but then a voice called out to her. "Applejack? Is that you?" A female voice said.
Applejack turned around, and saw two ponies she swore she would never see again. "...Ma! Pa!" Applejack said, as she and Apple Bloom suddenly embraced the two ponies. White Flame was nearby, smiling.
"...So, you reunited the Apple Siblings with their parents huh?" White Flame asked. "I'd say that's a big attornment you just made."
"Well, every pony deserves some amount of happiness. Even her." Black Heart said.
The double wedding took place, and with her magic horn, Fizzlepop Berrytwist provided some fireworks shortly after the Shadowbolts formation to celebrate the double wedding. Now, Spike and Smolder were over with Ember and her father.
"So...I guess now that the Double Wedding has happened, now maybe you can tell me what was just so important." Spike said.
"And anything you have to say to Spike, you can say to his wife." Smolder said. "...Heh. That rhymed."
"That's fine. It's just...have you ever wondered why you are able to access that monsterious dragon form whenever you desire to protect another?" Ember asked.
"I thought that just became a thing because I had Shining Armor as an adoptive brother." Spike said.
"I guess having the former captain of the Canterlot Royal Guard as your adoptive brother only helped push you towards that." Ember said.
"...It's just that this is difficult for me to admit but...Spike...I am your father." Torch said.
"...Hold up, sounds to me like you just said that you are my father..." Spike said.
"I did. You heard correctly. The ability to access that form to protect others is something Ember and I are capable of doing as well." Torch said.
"...Spike.mlp will stop working now..." Spike said before he fainted.
"...Here I go too..." Smolder said before she fainted.
But they weren't the only two who fainted that day: Shining Armor fainted as well when Flash Sentry just proposed to his biological sister right then and there.
