In a darkened realm where shadows pulse with a life of their own, an entity known as the Lifestream stands, weaving its intricate dance with threads of existence. This creature, the Lifestealer, has skin that shimmers like liquid silver and eyes that burn like eclipsed suns. It moves through the gloom like a whisper on the wind, drawing energy from the life force of everything it touches, leaving behind wilted plants and barren soil. Eternally hungry, it seeks the brightest souls, those whose essence can sustain its eternal journey through the void. Yet, within its gaze lies a melancholy longing, as if it remembers a time when it too was vibrant, seeking a way to reclaim that lost vitality without draining the world it once cherished.
