Renius slid onto his back, his chest barely moving. He looked like what he was, a frail old brown stick of a man, made hard but brittle in the Roman sun. As Marcus's gaze fell on him, he tried to rise, shuddering with weakness.

Marcus felt a hand press down on his shoulder, interrupting his rage as it grew again. Tubruk stood beside him, his face black with anger. Marcus could feel the ex-gladiator's hand shake slightly.

"Relax, boy. There'll be no more fighting. I have sent for Lucius and Gaius's mothers doctor."

"You saw?" Marcus stammered.

Tubruk tightened his grip.

"The end of it. I hoped you would kill him," he said grimly, looking over to where Renius bled. Tubruks expression was hard as he turned back to the newcomer.

"Who are you, ancient? A poacher? This is a private estate."

The old man stood slowly and met Tubruks eyes. "Just a traveler, a wanderer," he said.

"Will he die?" Marcus interrupted.

"Not today, I think," the old man replied. "It would not be right after I have arrived-am I not a guest of the house now?"

Marcus blinked in confusion, trying to weigh the reasonable sound of the words with the still-swirling pain and rage inside him.

"I don't even know your name," he said.

"I am Cabera," the old man said softly. "Peace now. I will help you."

Gaius lifted into consciousness, woken by angry voices in the room. His head pounded and he felt weak in every bone. Pain from below his waist heaved in great waves, with answering throbs at pulse points on his body. His mouth was dry and he could not speak or keep his eyes open. The darkness was soft and red and he tried to go back under, not yet willing to join the conscious struggle again.

"I have removed the perforated appendix and tied off the severed vessels. He has lost a great deal of blood, which will take time to be replenished, but he is young and strong." A stranger's voice-one of the estate doctors? Gaius didn't know or care. As long as he wasn't going to die, they should just leave him alone to get well.

"My wife's doctor says you are a charlatan." His father's voice, no give in it.

"He would not operate on such a wound-so you have lost nothing, yes? I have removed the appendix once before; it is not a fatal operation. The only problem is the onset of fever, which he must fight on his own."

"I was taught that it was always fatal. The appendix swells and bursts. It cannot be removed as you might cut off a finger." His father sounded tired, Gaius thought.

"Nevertheless, I have done so. I have also bandaged the older man. He too will recover, although he will never fight again, with the damage to his left shoulder. All will live here. You should sleep."

Gaius heard footsteps cross his room and felt the warm, dry skin of his father's palm on his damp forehead.

"He is my only child; how can I sleep, Cabera? Would you sleep if it was your child?"

"I would sleep like a baby. We have done all that we can. I will continue to watch over him, but you must get your rest." The other voice seemed kind, but it did not have the rounded tones of the physicians that tended his mother. There was a trace of a strange accent, a mellifluous rhythm as he spoke.

Gaius sank into sleep again as if he held a dark weight on his chest. The voices continued on the edge of hearing, slipping in and out of fever dreams.

"Why have you not closed the wound with stitches? I've seen a lot of battle wounds, but we close them and bind them."

"This is why the Greeks dislike my methods. The wound must have a drain for the pus that will fill it as the fever strengthens. If I closed it tight, the pus would have nowhere to go and poison his flesh. Then he would surely die, as most do. This could save him."

"If he dies, I will cut your own appendix out myself."

There was a cackle and a few words in a strange language that echoed in Gaius's dreams.

"You would have a job finding it. Here is the scar from when my father removed mine many years ago- with the drain."

Gaius's father spoke with finality: "I will trust your judgment then. You have my thanks and more if he lives."

Gaius woke as a cool hand touched his forehead. He looked into blue eyes, bright in skin the color of walnut wood.

"My name is Cabera, Gaius. It is good to meet you at last and at such a moment in your life. I have been traveling for thousands of your miles. It is enough to make me believe in the gods to have arrived here when I was needed. No?"

Gaius couldn't respond. His tongue was thick and solid in his mouth. As if reading his thoughts, the old man reached over and brought a shallow bowl of water to his lips.

"Drink a little. The fever is burning the moisture from your body."

The few drops slid into his mouth and loosened the gummy saliva that had gathered there. Gaius coughed and his eyes closed again. Cabera looked down at the boy and sighed for a moment. He checked that there was no one around and then placed his bony old hands over the wound, around the thin wood tube that still dribbled sluggish fluid.

A warmth came from his hands that Gaius could feel even in his dreams. He felt tendrils of heat spread up into his chest and settle into his lungs, clearing away fluid.

The heat built until it was almost painful, and then Cabera took his hands away and sat still, his breathing suddenly harsh and broken.

Gaius opened his eyes again. He still felt too weak to move, but the feeling of liquid moving inside him had gone. He could breathe again.

"What did you do?" he murmured.

"Helped a little, yes? You needed a little help, even after all my skills as a surgeon." The old face was deeply lined with exhaustion, but his eyes still shone out from the dark creases. The hand was pressed against his forehead again.

"Who are you?" Gaius whispered.

The old man shrugged. "I am still working on an answer to that. I have been a beggar and the chief of a village. I think of myself as a seeker after truths, with a new truth for each place I reach."

"Can you help my mother?" Gaius kept his eyes closed, but he could hear the soft sigh that came from the man.

"No, Gaius. Her problem is in her mind, or the soul, perhaps. I can help a little with physical hurt, but nothing more. It is much simpler. I am sorry. Sleep now, lad. Sleep is the real healer, not I."

Darkness came, as if ordered.

When he woke again, Renius was sitting on the bed, his face unreadable as always. As Gaius opened his eyes, he took in the changed appearance of his teacher. His left shoulder was heavily bound close to the body and there was a pallor under the sun-darkened skin.

"How are you, lad? I can't tell you how good it is to see you getting better. That old tribesman must be a miracle worker." The voice at least was the same, curt and hard.

"I think he may be, yes. I'm surprised to see you here after almost killing me," Gaius murmured, feeling his heart pump faster as the memories came fresh. He felt sweat break out on his forehead.

"I did not mean to cut you badly. It was a mistake. I am sorry." The old man looked into his eyes for forgiveness and found it there waiting for him.

"Don't be sorry. I am alive and you are alive. Even you make mistakes."

"When I thought I'd killed you…" There was pain in the old face.

Gaius struggled to sit up and found, to his surprise, that his strength was growing. "You did not kill me. I will always be proud to say it was you who trained me. Let there be no more words on this. It is done."

For a second Gaius was struck by the ridiculousness of a thirteen-year-old boy comforting the old gladiator, but the words came easily as he realized he felt a genuine affection for this man, especially now he could see him as a man and not a perfect warrior, cut from some strange stone.
