As they stumbled out of the portal, the group found themselves in the grand hall of Bilskirnir. Hearthstone glanced around, taking in the glowing light and shimmering walls.

Samirah, clutching her hijab, noticed the movement in the baby sling. She smiled as Hero's light gray eyes peeked out, looking around curiously.

Hearth reached out, gently stroking Hero's cheek. The baby gurgled happily, reaching out a chubby hand to grasp at Hearth's fingers.

Suddenly, the goddess Sif appeared. Her golden hair cascaded around her shoulders, and her eyes sparkled with an inscrutable light.

Sif's gaze settled on Hearth. She extended her hand, revealing a set of wooden runes. "These are for you," she said, her voice echoing through the hall.

Hearth accepted the runes, examining them with care. He felt a strange sense of power emanating from the wooden symbols.

Sif warned Hearth about the 'inheritance' rune. "You'll need to find it to unlock your potential," she said, her gaze serious.

Magnus, still clutching his pendant of Frey, watched the exchange with interest. He felt a sense of impending adventure stirring within him.

Blitzen, meanwhile, was busy examining the architecture of Bilskirnir. His eyes darted around, taking in the intricate designs and craftsmanship.

Samirah looked at Magnus, her eyes filled with determination. "We need to find that rune. For Hearth, for Hero, for all of us."

Hearth nodded, his hand still holding onto the runes. He knew that the task wouldn't be easy, but he was ready to face any challenge.

Blitzen joined the group, his gaze serious. "We'll need a plan," he stated, his gaze flickering to each member of the group.

Magnus nodded, his mind already whirring with strategies. The son of Frey had faced giants and monsters before. He was ready to do it again.

Samirah, Magnus, Blitzen, and Hearthstone huddled together, discussing their plans. Hero, now awake, watched them with wide, curious eyes.

They knew the journey would be fraught with danger. Yet, they also knew they had each other. They were ready to face whatever lay ahead.

With a final nod of agreement, they turned to leave. As they did, Sif's voice echoed behind them. "May the gods be with you," she said.

They stepped back through the portal, emerging in the shadow of the rowan tree. As they looked around, they knew their quest had truly begun.

Hearth cradled Hero closer to his chest, promising to keep him safe. The baby responded with a gurgle, his gray eyes twinkling with delight.

Blitzen gave Hearth a supportive nod, clasping his hand in a firm shake. They had become a family, and they would face this together.

Samirah and Magnus led the way, their eyes scanning the horizon for any signs of danger. They knew the path would not be easy, but they were prepared.

The quest for the 'inheritance' rune was underway. With each step, they moved closer to their goal, and the destiny that awaited them.

As they moved forward, the group could not help but feel a sense of anticipation. They were embarking on a journey that would test them in ways they could not imagine.

But with every challenge, they knew they would grow stronger. As they set off on their adventure, they were ready to seize their destiny.

They were not just a group of misfits anymore. They were a team, a family. And together, they were ready to face the runes of destiny.

As they disappeared into the distance, the rowan tree rustled in the wind, as if whispering a silent prayer for their safe return. The quest had begun.
