I am, in truth, a yellow fork From tables in the sky By inadvertent fingers dropped The awful cutlery cry. Of mansions never quite disclosed And never quite concealed The apparatus of the dark To ignorance revealed. What am I?

“Sunshine”

Sunshine is associated with warmth and light, but it does not relate to the idea of a 'yellow fork' or the 'awful cutlery cry' which suggests something sharp and sudden like lightning.

“Gold”

Gold may be yellow and valuable, but it doesn't fit the imagery of being dropped from the sky or being associated with the idea of revealing darkness, which aligns with the nature of lightning.

“Star”

Stars are often depicted as bright and illuminating, but they do not have the characteristics of a 'fork' or a 'cutlery cry' and do not fall from the sky in the same impactful manner as lightning.
