Introduction
What? Did I mislead you? I'm really sorry... Okay, I'll take this research more seriously and I'll visit a few friends. Maybe Sor Choubard will be able to help me. No, no, I've cost you too much time already; now I have to repair my mistake. I should've known it wouldn't be so simple. But there was a phelaguial. Oh, I think you should go back to see Eiron, he may have hidden something from you... You never know with these old fools. Then come back and we'll share our findings.

Agina and Yoran? Yes, that matches what I've found. If Eiron didn't make fun of you this time, I think we can say for sure that Yoran Silenus was the great kronotras master. Thanks, this is quite helpful for my research... It sheds new light on the first colony's old families.
