King Jaehaerys I makes peace with Rogar Baratheon

«[Rogar Baratheon] asked if the king would require hostages of him, as a surety of his future loyalty. Three of his brothers had young children who could be sent to court, he pointed out. In answer, king Jaehaerys descended the Iron Throne and bade Lord Rogar follow him. He led his lordship from the hall to the inner ward where Vermithor was being fed. A bull had been slaughtered for his morning meal and lay upon the stones charred and smoking, for dragons always burn their meat before consuming it. Vermithor was feasting on the flesh, tearing loose great chunks of meat with each bite, but when the king approached with Lord Rogar, the dragon raised his head and gazed at them with eyes like pools of molten bronze. “He grows larger every day,” Jaehaerys said as he scratched the great wyrm under his jaw. “Keep your nieces and your nephews, my lord. Why would I need hostages? I have your word, that is all that I require.”»
