While Leon and Crik were convincing the other mithril people to join the fray, he realized that Crik's people didn't grow all that much in those years. In fact, that whole species was in a state of stagnation. They became a warrior race, but thanks to Ilyana, they didn't have to fight anymore, and now that they had a new planet to call home, they lost the sole goal that kept them moving for hundreds of years.
Leon didn't know that before, but the mithril people were near immortal with their new bodies. However, immortality was like a curse to those who couldn't find a new goal and could only feel a limited number of things. They had the chance not only to recover their home planet and to become beings that could feel the taste of a good meal again… with those prospects, every single person on that planet accepted Leon's invitation.
Congratulations! You have become a Level one Diplomat!
