In Defenders of Ulthuan and Sons of Ellyrion, Ulthuan comes under attack from an alliance of the traitorous dark elves and Chaos-corrupted Norscans. As the great heroes of the high elves - Tyrion, Teclis and Eltharion among them - rally their armies, the fate of the land lies in the hands of Eldain and Caelir, brothers separated by fate and treachery. In Guardians of the Forest, the noble Bretonnian knight Leofric is thrown into an uneasy alliance with the wood elves as they battle a plot by monstrous beastmen to corrupt the sacred groves of Athel Loren and threatens not only the forest, but all of Bretonnia.
