And then, after thousands of years, Odin found the answer in his own Realm, again. The long battle with the Jotuns had finally come to an end, the Aesir gods had completely eliminated the ferocious giants. The last mages of the Jotun tribe could not stand Odin's barbaric torture and revealed information about the Mytheria - the pure energy that governs the power of gods and creatures throughout the world. Odin realized that not only in his Nine Realms but other realms were also overflowing with the powerful vitality of the Mytheria. Without that energy, anywhere would become a dead land, and Thor's conquests so far have yielded nothing because of that. And so, the supreme god decided to bring the seeds of the Yggdrasil tree to other gods to usurp the last drop of the Mytheria to strengthen his eternal power - which could help him keep the Nine Realms. instead of watching it fade away after Ragnarok.
