"No one knows how Thrud identified and awakened the hidden potential of your dormant bloodlines." Lith said. "Even with Ufyl's help, isolating the markers that allowed him to evolve into a Seven-Headed Dragon might take decades.
"Replicating the process without the use of Forbidden Magic is going to require even longer. If you accept to take part in the research, however, by comparing the life forces of the members of your family with yours, the Hydras should be able to spot what you all have in common.
"At that point, they'll be capable of programming the Harmonizer to trigger a specific bloodline instead of reshaping the entire life force.
"The effect would only last while the subject is above a mana geyser, but by studying the changes during the forced evolution, the Hydras can find a way to make it permanent if not even to awaken a dormant bloodline without the Harmonizer.
"You would help Ufyl, your families, and the beast Council."
