N is for Naga

Nagas are semi-divine serpent creatures in Hindu and Buddhist mythology. They're often human above the waist and snake below the waist, although they can be entirely snake or entirely human. The nagas are so numerous that they live under the sea in jeweled palaces. Some act kind and wise, while others act like demons. And since the nagas oversee the distribution of the rain, it's generally good to treat them respectfully.
