Karl Cullinaine, Walter Slovotsky and several companions leave Home — the town they’ve built in this world of dragons and magicians to which they have been transported — to continue their fight against slavery. Karl is helped by the faithful and enormous flying dragon Ellegon, with whom he can communicate telepathically. Karl is also on a mission to provide protection to the wife and son of a royal family, whose land and castle are under attack by slave-raiding forces. Fierce fighting and surprises are in store for Karl and his friends, as they fight to defend the kingdom under siege.
