Longer night

When the guards took the body they escorted me to the local infirmary where I had to be treated for my wounds and given an antidote for the poison before it fully set in. There I had met up with Mystery again, she was already bandaged up and resting so it was best not to bother her anyway. I stayed up for the rest of the night watching the sun rise overhead as the festivities had finally come to a close, yet, those last words rang out, echoing in my mind, "my queen...made...the right...choice…." what did he mean by those words? Was he referring to some sort of queen in the Underdark? Some secret hidden ruler? What could he have meant by those last dying words?
