The Calling (Dragon Age)

After two hundred years of exile, King Maric has allowed the legendary Grey Wardens to finally return to Ferelden. When they come, however, they bring dire news: one of their own has escaped into the Deep Roads and aligned himself with their ancient enemy, the monstrous darkspawn. The Grey Wardens need Maric's help, and he reluctantly agrees to lead them into the passages he traveled through many years before, chasing after a deadly secret that will threaten to destroy not only the Grey Wardens but also the kingdom above.
