After Colton Highmore is gone, Duke Sanguine turns toward Amachi. Even though his status is above the healer, he keeps his voice polite. "Take a look at the guests who have experienced the blood thrall."
Amachi heaves a sigh. He wants to leave this place, but he can't. The guests are experiencing the aftereffects of the blood thrall. Even if Amachi is a healer, he has the power to decline him. That's the boon that he asked the king for saving his life. As a healer who is at the scene, he can't decline the Duke's request.
These royal asses only know how to whine anyway. Amachi goes to Duke Sanguine's youngest daughter. Belinda is too young to go through a blood thrall without experiencing the aftereffects.
