Knight of Shadows, Ch. 6
Lord Borel, a duke of the royal House of Swayvill and reputedly one of my mother's lovers of long ago. He was also deemed to be one of the deadliest swordsmen in the Courts. 

More on Lord Borel here.

Prince of Chaos, Ch. 1
I knew he was a noble of the Courts, and I searched my memory. Of course. It had been a long while, but now I recognized him. It was Tmer, of the House of Jesby, eldest son of the late Prince Rolovians, and now lord himself of the Ways of Jesby - spade beard, heavy brow, sturdily built, not unhandsome, in a rugged sort of way; by all report a brave and possibly even sensitive fellow.

Then there was Prince TubbIe of the Ways of Chanicut, phasing back and forth between human and swirling demonic forms. Placid, heavy, subtle; centuries old and very shrewd; he wore a fringed beard, had wide, innocent, pale eyes, was master of many games.

Prince of Chaos, Ch. 2
"When you say 'the Crown,' who, exactly, are you referring to, right now? Who's making decisions in the interim?"

"Lord Bances of Amblerash," he replied, "a distant relative and longtime friend of our late monarch."

"I sort of recall him. Could he have an eye on the throne himself, and be behind any of the-removals?" 

"The man's a priest of the Serpent. Their vows bar them from reigning anywhere."

Prince of Chaos, Ch. 3
"I'd heard as much in Amber," I said. "I wonder. . . He'd killed a noble - a Lord Borel - near the end of the final battle. Any chance Borel's relatives might have gone after him?"

He clicked his fangs twice, then pursed his lips.

"The House of Hendrake . , ." he mused. "I think not. Your grandmother was Hendrake. . . ."

"I know," I said. "But I didn't have much to do with them. Some disagreement with Helgram. . . ,"  ...

"Who is head of the House of Hendrake now?" 

"The Duchess Belissa Minobee."

"The duke, her husband - Larsus. . . . What happened to him?"

"He died at Patternfall. I believe Prince Julian of Amber slew him."

"And Borel was their son?" 

"Yes. ... Borel had two brothers, a half brother and a half sister, many uncles, aunts, cousins. Yes, it's a big House."

Prince of Chaos, Ch. 3

"The House of Hendrake . , ." he mused. "I think not. Your grandmother was Hendrake. . . ."

"I know," I said. "But I didn't have much to do with them. Some disagreement with Helgram. . . ," 

"Hendrake Ways is very much of the military sort," he went on.  ...

"Who is head of the House of Hendrake now?" 

"The Duchess Belissa Minobee."

"The duke, her husband-Larsus. . . . What happened to him?"

"He died at Patternfall. I believe Prince Julian of Amber slew him."

"And Borel was their son?" "Yes."

"Ouch. Two of them. I didn't realize."

"Borel had two brothers, a half brother and a half sister, many uncles, aunts, cousins. Yes, it's a big House."

Prince of Chaos, Ch. 4
"What can you tell me about my mother's maternal side, the House of Hendrake?"

... "They're into soldiering, professionally," he said. ... "Belissa Minobee's been in charge since General Larsus's death." 

Prince of Chaos, Ch. 10
"I'm not really clear on it," I said. "I don't know Dara's status right now in her father's House -- Helgram -- or her mother's -- Hendrake. But it might be worth a power struggle within Sawall if that's where the next king is coming from. Still, the more I learn of Mandor the more intimidating such a struggle would seem. I'd guess they're cooperating."

Prince of Chaos, Ch. 10
At the circle's center Gerard faced a demonformed son of Hendrake, of his own height and greater girth. It looked to be Chinaway himself, who was said to have a collection of over two hundred skulls of those he'd dispatched.

Geography of the Courts of Chaos

Prince of Chaos, Ch. 7
He caught hold of my arm and we were transported, arriving at the inward edge of the Plaza at the End of the World, where a blue sky darkened above a conflagration of mourners milling along the route the procession would take. We passed among them, in hope of being seen by as many as possible. I was greeted by a few old acquaintances. Unfortunately, most wanted to stop and talk, not having seen me for some time. Jurt had similar problems. Most also wondered why we were here, rather than back at the Thelbane, the massive, glassy needle of Chaos far to our rear. Periodically, the air would vibrate as the gong continued its slow sounding. I felt it in the ground, also, as we were very near to its home. We made our way slowly across the Plaza, toward the massive pile of black stone at the very edge of the Pit, its gate an archway of frozen flame, as was its downward stair, each tread and riser time-barred fire, each railing the same. The rough amphitheater below us was also fire-furnished, self-illumed, facing the black block at the end of everything, no wall behind it, but the open emptiness of the Pit and its singularity whence all things came. ...

Prince of Chaos, Ch. 8
Growling, I adjusted my apparel, focused my attention on the Temple of the Serpent, and bade the spikard deliver me near its entrance. It performed as smoothly and gently as if I had never doubted it, as if I had not dis-covered in it yet another cause for paranoia. k And for a time, I simply stood outside the doors of frozen flame, there at the great Cathedral of the Serpent at the outer edge of the Plaza at the End of the World, situated exactly at the Rim, opened to the Pit itself- where, on a good day, one can view the creation of the universe, or its ending-and I watched the stars swarm through space that folded and unfolded like the petals of flowers; and as if my life were about to change, my thoughts returned to California and school...
