"Well, there was one person who was able to master hopping between the two dimensions," Tomoko said matter-of-factly. "This person sought to defeat the madman, as he attacked his people. This person... the legends call him Tal'Set. We don't know if that's true or not, but it works for now."
She flipped open the napkin she was drawing on and continued her sketch, though no one could make heads or tails of it just yet. "Tal'Set was the one who found the Chronoscepter. With it, he was able to gain access to the madman's fortress and defeat him in single combat. From there, he destroyed the amplification array and stopped another threat to the Multiverse. He went back to his home and continued his good deeds with the Chronoscepter. But Tal'Set knew that there would be more people looking to harness its power, and he was growing on in years. He couldn't protect it forever."
Another flip of the napkin, unfolding it completely. Again Tomoko continued her sketch while her tale went further. "So, he did the one best thing to make sure it wouldn't happen. He tried to destroy the Chronoscepter. To weaken it structurally, he dismantled it into eight pieces, and threw them into a volcano. Sounds like a good idea, right?"
She laughed a bit. "Too bad he didn't know that the weapon is virtually indestructible. And, well, volcanoes have to erupt sometime. And it did erupt, with untold force. The eight pieces were scattered in the eruption."
