After Reavaer had to leave the world of Rialar to be trained as a real world guardian of the Exi, a dimension-jumping people, he returns after several years. However, he appears in a place unknown to him. Reavaer has to find his way around, find loyal allies with whom he has to assert himself against many an inhabitant, defeat rulers and investigate mysterious anomalies. To do so, he must use all the knowledge and experience he has gained on his travels. The world of Rialar is still as harsh and ruthless to its inhabitants as he had come to know it. But Reavaer knows that not all of his allies are what they seem. Nor will everyone agree with his vision as a Guardian.
