In Avalonia, a land surrounded by an endless wall of mountains, Jaeger Clade and his son Searcher are adventurers who brave the wilderness to explore new worlds. While trying to traverse one of the mountains, Searcher discovers a plant that gives off green energy. Jaeger insists on continuing the quest, but Searcher and the rest of the expedition team believe that the new plant, dubbed Pando, is good enough. Jaeger angrily continues his mission alone.

Twenty-five years later, Searcher has made a name for himself by harvesting Pando and turning it into a fuel resource for Avalonia. He is married to fellow harvester Meridian and they have a son named Ethan who gets embarrassed whenever Searcher tries talking to his crush Diazo.
