Darcia's response leaves Khallyon speechless, not because it seems exaggerated to say that they will be together for all eternity, but because the Dragoness is actually perpetual, but that doesn't apply to the Rogue Cadet, who will eventually leave depart from this life.
{No, If the Åyûrïc Emperor managed to live for so long, I can do it too… , Also, the Dragons are not the only Species with Perpetuity…}
•"So be it Darcia, I will be with you for Eternity"•
•"You better mean it Khallyon, Or I will go, find and beat you up in the Afterlife…"•
Darcia's gaze says it all, she is going to put all her trust in Khallyon, as the meaning of the previous words carry a real weight for her, the Young Man is aware of it, and he is not going to disappoint her.
The Rogue Cadet unclasps the pincer hook, releasing the Dragoness neck, as he tugs back part of the leash so he doesn't has to deal with the shortened length due to his own machination.
