When the king, Valyr I, came to Myrna, there was a parade in the snow and Edwin was called to the mayor's office. Hadrian did not understand why. Surely if the king wanted to be treated, he would just go to his personal healer, lord Ruthheaven?
But Hadrian refused to let Edwin meet the king alone, and so, he had stated his arguments carefully. Hadrian had dirt on the king, and that dirt could prove useful to negate any demand the king had of Edwin.
More than that, Hadrian was a skilled fighter, and the stables were not too far from the apartment, should they need to get away.
All the while, Edwin had regarded him with an uncharacteristic coldness. He knew something about the meeting, Hadrian did not, but no matter how much Hadrian whined, he did not share his knowledge.
