Brownie in the Fairy Realm

https://solitarypaganism.com/fairy-magick/brownie-in-the-fairy-realm/
A household spirit popular in northern English and Scottish folklore, the brownie is a very small, brown, shaggy human and usually dresses in ragged brown clothes.

Brownies are considered to be most industrious when it comes to such household chores as grinding grain, churning butter, and plowing.

They love to help humans with their work, especially with tedious tasks.

Brownies are thanked with a bowl of fresh cream and freshly baked bread.

If criticized, they will undo what they have already done and destroy a good deal more.
