This part of the city forest up to Hastenrath is the Killewittchen, and this poem explains why it should be so
There is another similar story that ends more dramatically. Unfortunately, I don't know which one is the right one.
Killewittchen
A long, long time ago the Killewittchen lived in a large rock cave not far from the village of Hastenrath.
There was a large limestone rock there that contained a cave with small stone benches.
The Killewittchen were little dwarfs who never showed up during the day. They did their work at night and did not want to be seen.
The Hastenrathers knew this and left them alone, because the people were doing well.
At the time of harvest it often happened that the ripe fruit that was still on the stalks in the evening was cut off and stood in heaps.
People knew right away who had done that. Whoever left his plow in the field found his field freshly plowed in the morning.
In their work, the Killewittchen especially supported the farmers who had their fields near their underground homes.
One day the Killewittchen were gone; where they turned and why they left is not known.
It is only said that before they left they rummaged in the earth for a long time, packed their rich treasures in sacks and took them with them on their journey.
The Killewittchen were related to the Heinzelmännchen from Cologne
