Illuga saga Gríðarfóstra is a fornaldarsaga about a young Dane named Illugi who delivers a female troll and her daughter from a curse. The earliest manuscript (of 36 which are known to exist) dates from the first half of the 16th century (AM 123 8vo).

When he had crossed the fjord, he found a cave and soon encountered its inhabitant. It was a troll woman named Grid. She could not be called beautiful, in fact she was hideous. When Illugi said that he came searching for fire, she replied that he would get none unless he said three truthful words fast, and slept with her daughter.
