Erich continued to chill with Ayumi and Erika, while Tia worked hard to put together information on the Sages and their whereabouts. It was difficult to track them, due to the fact that there were so many elves in the galaxy, and the fact that they had long since prepared for this reality.
Because of this, Tia had begun conducting experiments on the side. That might help increase Erich's ability to see into the future, and perhaps counter the Sage's with his abilities. After Thyrin had jumped to his death, Tia requested from the Asuran Despot to gather what remained of his body, and hand it over to Erich's crew.
Tia had been conducting experiments on Thyrin's blood and tissue samples to see if there was something unique about their biochemistry when compared to the average Elf. After all, she had not been able to find any actual signs of Erich being any different from the standard Germanic male, despite the fact that he shared similar abilities to the Sages.
