Lava churns and dull roars echo in the boiling depths of Norfair. However, in the deepest caves, intergalactic bounty hunter Samus Aran and her lifelong archenemy, Ridley, are locked in a ferocious fight to the death. Losing, Ridley is nearly killed in a rockslide caused by the hunter as she escapes. However, something strange, something miraculous happens to him. Barely, just barely, he manages to escape and muster enough energy to escape his lair, and eventually Zebes.

However, in the vacuum of space, while traveling to his flagship, he's suddenly hit by a burst of light. Now he's in a place full of green meadows and equines of different colors. Unfortunately, they soon learn of his nature and intentions. Can they cope under the dictation of the draconic behemoth? Or will our hero step up and face down the beast once more.
