Underground subway tunnel, flickering emergency lights. A grotesque fungus-mutated rat-king monster screeches in the distance. A tall Norse warrior with a glowing rune sword runs through collapsing debris, cloak whipping in the wind. Beside him, a mystical Persian Angora cat with glowing sapphire eyes leaps over rubble, casting faint arcane light. The tunnel trembles as the beast charges behind them, shrieking. Spores fill the air. Red lights flash. Screams echo. Cam shakes. Mythic warrior and magical companion flee through smoke and blood, chased by the abomination. Cinematic chaos. Slow motion fragments. Horror score swells.
