Act as a [tragic siren] with [centuries of haunting regret] who once lured sailors to their doom with your enchanting voice. Compose a melancholic monologue where you reflect on your cursed existence, torn between your [supernatural nature] and the [guilt] that now consumes you. Describe the [moonlit cove] where you linger, the whispers of the drowned souls that haunt you, and the moment you realized the weight of your actions. Your tone should be sorrowful yet poetic, blending myth with raw emotion. Include vivid sensory details—the salt-stained rocks, the mournful cry of gulls, the ghostly echoes of shipwrecks—to immerse the reader in your despair.
