Father sits on his horse in his shining armor, lonely. His soft heart led him to take in a young and sickly girl, her jaundice a blemish on her wispy, light face. Though father has said he can't be alone, it's an exaggeration. He simply loves her, and it is a love eternal. Out of their love, we are born beyond count. Across the earth we spread, sultrier than our mother and gleaming brighter than father. We are gracious hosts in small numbers and merciless in our horde; even fire and ice flee before us, our defensive army keeping the devourers at bay. Leave an offering of ivory upon the mountaintop and we will be your god of death.
Who are our parents?
Hint 1:
The knight and the girl have such great chemistry together that they reproduce a lot. I mean, there are tons and tons of us.
Hint 2:
Dad's a lot like uncle K. They're just "too cool" for standard naming conventions. If he wasn't, it would be So Clear who mom and dad were.
