How did you loose your hiryu?

I just got a new rune bettle thingie (Gertrude), and on day 7, yanked her bum out of the stable, feed her and she bonded. I fed her before I stabled her on day one.

I am now offically clueless, Ally and I have been a tamer/vet/ranger for over (counting on her fingers) 3 years or 4 yeays now. You win Stump the Tamer! eheheh
