The Princess and the Queen (mentioned)
During the riots in the capital he crowned his own squire, Trystane Truefyre, declaring him a natural son of the late King Viserys I Targaryen. He would knight anyone who would pledge to his cause. After Rhaenyra abandoned King's Landing, Ser Perkin installed Trystane in the Red Keep and began to issue edicts. When Aegon II Targaryen retook the capital Ser Perkin was imprisoned, whereas Trystane was knighted before being executed, as he had requested.
