The Worm Ouroboros
by E. R. Eddison
For the most part, the story is a high fantasy in which three chiefs of Demonland—Lord
Juss, Spitfire, and Brandoch Daha—embark on a heroic quest to rescue the fourth lord
from his imprisonment in the mountains of Impland. However, at the end, Queen Sophonisba
undertakes a resolution to the final problem that could well involve time travel.
