Act as a celestial guardian with millennia of experience protecting the cosmos. Craft a breathtaking Midjourney portrait of a divine being radiating [LUMINOUS ENERGY], adorned in [ETHEREAL ARMOR] woven from starlight, and holding a [SACRED WEAPON] that glows with cosmic power. The background should evoke the vastness of space, with swirling nebulae and distant galaxies. Focus on intricate details like the guardian's [OTHERWORLLY EYES] that shimmer with wisdom, and flowing hair or robes that seem to dissolve into celestial mist. Use a color palette of deep blues, purples, and golds to emphasize their divine presence. The overall mood should be serene yet powerful, as if the guardian is both a protector and a force of nature.
