Atop a house in Oslo's northern suburbs… a black whirlwind hovered silently. Standing resolute was the last Viking of the age, clad in heavy, razor-sharp black steel. His right hand gripped a colossal battle axe capable of cleaving any foe in two, while his left held a heart-gouging dagger. A flash of silver peeked from beneath his leather jacket—a mythril tunic thrumming with dense magical energy.
Beside him hovered a testament to the lost era of arcana and fantasy: a silver-haired maiden, the last Valkyrie. Runes of flight kept her aloft, her form clad in shimmering magical armour. Her hands grasped the transformed form of a grand harp—a mythril halberd. Even under the starless night sky, the silver threads of her hair seemed to sparkle brilliantly, framed by a headdress adorned with a dragon's horn.
