She became most upset when the Lower World was drowned in a primordial flood. But she managed to save most of the inhabitants, leading them to the Upper World.
Amongst her rescued possessions was a sackful of stars which she gave to Beetle for safe-keeping, but he upset them and managed to spill stars all across the sky.
UTSET rushed off to pick them up, but only managed to grab a few planets when she realized she’d left a lot of upset people behind with no means of sustenance.
She was so upset by this that she hurtled back and planted pieces of her heart in the ground. These grew and flourished and became corn plants. What a sweet gesture. Spare a thought for UTSET the next time you tuck into a juicy corn-on-the-cob.
