Act as a seasoned fantasy writer with expertise in character development. Craft a detailed backstory for a shapeshifter who has lost all memory of their original form due to [PROLONGED SHAPESHIFTING], [TRAUMATIC EVENT], or [MAGICAL CURSE]. Describe their internal conflict, how they navigate the world without a true identity, and the [UNIQUE ABILITY] or [WEAKNESS] that sets them apart from other shapeshifters. Include their [CURRENT FORM'S INFLUENCE] on their personality and how they seek (or avoid) reclaiming their lost self. Keep the tone [MOOD: e.g., melancholic, mysterious, or desperate].
