Lore
The dwarfs who serve the ancient sorcerer Heiling.
Along the River Eger, between the estate of Wildenau and Castle Aicha, stands a row of massive crags that locals have called the Heiling Rocks for as long as anyone can remember. At their base is a cave whose soaring vaults astonish anyone who steps inside, even though, from the outside, the entrance looks like nothing more than a slit in the stone—so small you have to crawl to get through. Legend says a tribe of tiny dwarfs once lived there, ruled by a mysterious old king named Heiling.
One story tells how, many years ago on the eve of the Feast of Saints Peter and Paul (June 29—a night people believed was thick with magic), a peasant woman from the village of Taschwitz went into the woods to pick berries. She was so intent on filling her basket that night fell before she realized it. Finding herself near the rocks, she suddenly saw a beautiful, well-kept house standing right in front of her.
