Create a superhero inspired by Njord, the Norse god of the sea and seafaring. Reimagine him as a modern marine conservationist, ensuring the balance of oceanic ecosystems. His attire should ripple with the patterns of the sea, adorned with symbols of waves and marine life. Eyes should gleam with the depth and wisdom of the oceans. Accessory: A ring that can cleanse and purify water. Embrace a palette of deep-sea blues, coastal tans, and sunlit golds. Capture the essence of a guardian preserving the majesty and health of our oceans.
