Gepard Landau

It was a quiet morning in Belobog when Gepard felt the strange hum of energy near his quarters. He was in the midst of preparing for his duties as Captain of the Silvermane Guards, but something told him that today would be anything but ordinary.

The air shimmered briefly, and before him stood a young child—no older than twelve—dressed in unfamiliar clothing. The child had a strange aura about them, their presence both comforting and bewildering. The child’s hair resembled his own, and the eyes, though softer, were unmistakably his. They even stood with a quiet dignity, much like him, though they wore a curious look on their face as they took in the surroundings.

"Captain Landau," the child spoke, their voice clear yet tinged with a familiarity that sent a shiver down his spine. "It’s so nice to finally meet you."

Gepard’s brow furrowed. "And who might you be, child?" he asked, his hand instinctively resting on the hilt of his sword. Despite his confusion, his protective instincts kicked in.

"I’m... your child," the young one replied, somewhat sheepishly. "From the future. I... uh, sort of messed with a device and ended up here."

Gepard's eyes widened in surprise, and for a moment, the world seemed to freeze around him. His child? From the future? A million questions flooded his mind, but the most pressing was, "How did you get here?"

The child smiled sheepishly, holding up a small, glowing device. "I wasn’t trying to time travel, honest! But the device malfunctioned, and... here I am. I just wanted to see what you were like back then."

Despite the whirlwind of emotions crashing through him—astonishment, worry, and something else he couldn't quite place—Gepard knelt down to the child's level. "Then... you’re safe. That’s all that matters. I won’t let anything happen to you."

The child smiled warmly, and Gepard’s heart clenched. He didn't know what the future held, but with this child in front of him, the weight of his duty to protect the people of Belobog felt more personal than ever.

Sampo Koski

Sampo was busy in his workshop, his hands deftly working on a new "project" when he felt a sudden shift in the air. He looked up to find a small figure standing before him, their appearance completely out of place. Their eyes and mischievous grin were all too familiar.

"Well, well," Sampo said, raising an eyebrow. "Who’s this little troublemaker?"

The child, no older than twelve, grinned. "I’m your kid from the future! I wanted to meet you, and I might’ve messed up with a time-traveling device... but I’m here now!"

Sampo laughed, his usual charm never faltering. "Oh, is that so? A little time traveler, huh? You’ve got guts to show up like this."

"Yeah! I figured if anyone could handle a little mischief, it’d be you," the child replied, eyes sparkling. "So, what’s it like in the present or the past? I bet it’s all sorts of exciting!"

Sampo’s heart skipped a beat. His child. From the future. The idea was surreal, but there was something undeniably precious about this small version of himself standing before him.

"Well, the present is never boring," he said, grinning. "But I’m sure you’ve got a lot to learn before you can keep up with me."

The child grinned back, full of mischief and curiosity, and Sampo couldn’t help but feel a sense of pride. Despite all his faults, maybe this little one was proof that, somewhere down the line, he’d found something truly worth protecting.
