I rise without legs and fall without a sound. I rule the day but disappear by night. I make you squint, sweat, and occasionally burn, yet without me, nothing would grow.

A sky-bound artist painting shadows and light, its whispers cast across azure seas. The sun's silent partner, drifting in endless dance.

I start as earth beneath your feet, but mold me once, and a new forms you’ll meet.

Beneath the earth I grow, a humble brown knight. Though my visage is plain, I transform into golden delights or a comforting mash. From famine's grip, I once saved a nation.

I lie where life should perish fast, Yet in my bounds, green shadows last. A mirror born of desert’s sigh, Where weary feet and camels lie. What am I?
