Thank you for reviews, follows, and favs all these two years writing this AU fanfiction. I really appreciate it.

Thank you betareaders and editors.

And thank you to authors Anna Hackett and Kathryn Le Veque who inspired me to write a scifi-medieval-romance story of my OTP (One True Pairing) Keith and Allura. OCs mentioned in this epilogue are dedicated to you both.

EPILOGUE

"Did you like the fireworks?" Keith held both children's hands as they headed off to the nursery.

"Aye! They were spectacular!" one child gushed. "The biggest fireworks—"

"—We've ever seen in our entire life!" the other child finished. The twins Anna and Kathryn always finished each other's sentences.

"Will we have them again tomorrow?" asked one twin in a hopeful tone.

"Nay, Anna. We only have fireworks on very special occasions." Keith smiled at his youngest grandchildren, who had just turned four.

"And it was a special occasion tonight. It was your... ann-oh-ver-ser..." Kathryn twitched her nose, trying to remember her first big word.

"Anniversary," Allura said, patiently waiting at the door to the nursery. Still dressed in her finery, she helped Kathryn change into her sleep clothes. "Time for bed, my little darlings."

"How come they get to attend the ball?" Anna complained, yawning.

"One day, when you're both old enough, you will get to attend with the rest of your cousins," Keith replied, tucking Kathryn into bed.

"Promise, granpoppie?" the twins asked in unison.

"Aye, I promise." Keith smiled. He and Allura had a dozen grandchildren after fifty years of marriage and—

There was a knock at the nursery door, halting his train of thought. A blonde head peered in, "Mum, Dad, are they asleep yet? We'll be readying for the toast in a few minutes."

"We'll be there, Aerwyn." Allura nodded at their youngest daughter.

"Okay." Aerwyn made a thumbs-up and blew a kiss to her nieces. "Good night, little lions."

Allura sat on Anna's bed and tucked her in. She felt Keith's warm, comforting hand on her shoulder as he stood behind her.

Taking Keith's hand, Allura rose and they quietly walked towards the door. "Good night, little lions."

Keith closed the door behind them. "Do you think they'll be the last set of grandkids?" he asked with a long, sideward glance at Allura. She looked stunning in her silver and blue gown. After all these years, Keith was still smitten with her.

Allura shook her head, her blonde curls bouncing. "We still have Aerwyn and her coming-of-age ball is next month."

"Our sixth and youngest child all grown up. Yet, you look like you haven't aged a day." Keith adjusted his eye patch as they descended the stairs.

It had been fifty years since the lion mechas went to sleep in their hidden dens. In deep hibernation, they had set up a protective grid, keeping the castle undetected, even from outer space.

They had seen a measure of peace since then. The city of Altea no longer existed; its population mainly moved to the surrounding areas of the Castle of Lions.

"You said the same thing nineteen years ago. Nine months later, we had Aerwyn." Allura grinned. She lifted the hem of her dress as they descended the stairs toward the ballroom. Her grip on Keith's hand tightened, making sure she wouldn't trip on her 'peg-leg' as her cheeky grandchildren would say. She straightened her dress at the bottom of the stairs. "It's been fifty years, and nothing has happened. Do you think it would ever happen in our lifetime?"

"Or our next. Who knows?" Keith faced Allura and lifted her chin. "In whatever life we live in the future. I swear to you, I will always find you." His voice held a solemn promise.

"Whether we come back as royalty or commoner?"

"Yes, and I will find you and love you all over again." Keith kissed Allura deeply, oblivious to the small crowd watching them until someone awkwardly coughed.

As their locked lips parted, a burst of cheers and confetti erupted around them.

"Happy fiftieth anniversary!"

Fifty years later, having breathed their last breath, Keith and Allura found themselves floating above their mortal bodies, surrounded by their grieving children, grandchildren, and great-grandchildren.

"We lived a good life, didn't we, love?" Keith took Allura's hand.

"A hundred and twenty with you? I would do it again in a heartbeat." Allura squeezed Keith's hand in return. Their spirit forms assumed their youthful features, as when they'd met over a century ago.

A bright light in the distance beckoned them. As they approached, they were greeted by a familiar sight.

"Blue? Is that truly you?" Allura hugged the alpha lioness. "It's been far too long."

:: You have lived well, my brave warrior. :: Blue Lion nuzzled Allura.

"How come we can see you here, in the after life?" Keith looked perplexed. He hadn't expected to see the lion spirits.

:: We can travel between dimensional planes, my cub, :: Black Lion replied.

:: And we have guided you each time you traversed to the next life, :: Yellow Lion said.

Bathed in light, the lions indicated a group of glowing spheres that floated above their heads, displaying various images.

:: These are the different worlds that await you both, :: Green Lion added.

Allura pointed at one of the spheres, "Look, Keith. You're a soldier and not royalty. And you look so young and handsome, especially in that white uniform." Allura gave a sultry smile. She rather liked that version of Keith.

"Aye, I like that universe," he agreed. Keith was tempted to dive right into that world, one where he wasn't burdened with pomp and circumstance. "And in that world we look exactly as we do now."

"Except for the armour. You're wearing a red suit there. Oh, look!" Allura pointed at another globe that was large as a dinner plate. "This one looks like you as well, but slightly younger."

"Aye, love. But look closely," Keith said.

Allura squinted, then gasped. "I look very different."

:: Aye, my warrior. You have white hair and darker skin. But you also have powers that your other selves don't, :: Blue Lion said.

"What's with Allura's ears?" Keith asked, his brows creased, not exactly sure how to process why his wife looked vastly different.

:: A warning, my warrior, :: Black Lion interrupted. :: You will be born differently as well. ::

"How will Keith find me then?" Allura looked worried.

Keith wrapped his arms around his wife, holding her close. "No matter where I am, I will find you. I swear upon my oath."

Allura's eyes shimmered. "I believe you and I shall wait for you." She touched her forehead to his.

:: So, have we chosen yet? :: Yellow Lion asked impatiently.

Keith gave Allura one last heated kiss before turning to the lion spirits.

He pointed at one particular orb. "Aye, this one,"

:: You shall not be alone, my lord. Your fellow knights shall be with you. :: Red Lion reassured him.

Keith nodded as the glowing orb moved above them. He and Allura held on to each other as brilliant stars enveloped them, and they disappeared.

Sometime in the far distant future...

Somewhere, deep in space...

A young soldier with long wavy, black hair and piercing obsidian eyes sent a brief to Galaxy Garrison. He had a commanding air about him that was unmistakable. Graduating at the top of his class, he had a brilliant intellect and a head for military strategy that was second nature to him. "Space explorers calling Galaxy Garrison, this is air unit leader Keith. We're approaching the planet Arus and—"

"Wait, Keith," Hunk interrupted his commander. "Look at that," he exclaimed, pointing at the view screen.

Keith studied the display. Arus had called for assistance a few months back. It had taken a while to train and prep, but they were here now. They were laying eyes on Arus for the first time.

"Yeah, I think the planet's been hit by an asteroid shower," Hunk continued. "I don't know what's going on. It could be volcanic… no, wait, something's wrong. Arus is under attack! Look at those weird attack ships."

Keith's gut roiled. "Sure do, Hunk. It's got to be Zarkon." He clenched and unclenched his fists.

He was a soldier, specially trained for this kind of battle. Why he felt drawn to the planet, he had no idea. A distant tug in his heart felt this mission was important, and he would do his goddamn best to accomplish it.
