"Sosinna is a special child to me," Serra said before Xantcha's feet were on the floor. "I didn't know what had become of her. I'm grateful that you showed us where she was, even though I'm not grateful for your methods!"
The lady had Urza's voice, the voice of someone who treated everyone as children, someone whom mortals might mistake for a god. Xantcha had never been mortal, never believed in gods, and she'd used up all her graciousness.
"Sosinna didn't believe in mistakes, she never lost faith in you. All the time we were together on that forsaken, floating island, she was hoping you or Kenidiern would rescue her before the archangels came to kill her. If that was you who called the Aegis off, then when it comes to rescuing your special children, you cut very close to the edge." Urza was appalled. His eyes glowed dark. Kenidiern stared at his sandaled feet. "Things here aren't as perfect as she believed they were."
"You are Phyrexian, are you not?" Serra asked, a tone short of accusation.
Urza's displeasure rumbled through the empty part of Xantcha's mind. The important part, the part she'd kept for herself since Gix had taught her how to build mental walls, remained unbowed. "You know I am."
"Your leave, my lady," Kenidiern interrupted. "My love is in your hands now. There is no need for me to stay."
Serra dipped her chin. Kenidiern was in the air before she raised it again. There were only three of them left in the branch-framed chamber: a man and a woman with the powers of gods, and a Phyrexian newt. Well, Xantcha was used to being overmatched.
"There is no need for this, Xantcha." Urza attempted to impose peace. "I think Lady Serra will concede there have been certain imperfections in our condition here." He turned toward Serra.
"Your arrival was so unexpected-" Serra began.
Xantcha cut her off. "That reminds me. How did we get here? The last thing I remember was beating on the shell of a Phyrexian turtle."
"I destroyed that abomination and all the others," Urza answered quickly. "But my enemies were lurking, watching from nether places, and before I could escape, they sent
through reinforcements. It threatened to become the Fourth Sphere battle all over again, so I decided to retreat. I 'walked away, grabbing you as I left. But you were badly injured, and my grasp was not firm. I sensed the chasm to Phyrexia, of course-it is always there-but I sensed another, too, and threw myself across it. It was a terrible passage, Xantcha. I lost you. I would not have survived myself if Lady Serra had not found me and put me inside that cocoon you just saw.
"Such a marvelous artifact! If there is life, any life at all, the cocoon will sustain it and nurture it until the whole is healed. I am well again, Xantcha, well and whole as I have not been since I left Phyrexia, since before Phyrexia .. . since I met you. The principle is ingenious. To make her plane, Serra has treated time itself as a liquid, as a stream where water flows at different speed...."
Xantcha swallowed hard. It didn't help. She stopped listening to Urza ramble about the wonders of Serra's cocoon. His recounting of events was laced through with simplifications that were no better than lies: so I decided to retreat and I 'walked away didn't accurately describe what she remembered of Urza's Phyrexian invasion and was probably no better at describing how the skirmish with the turtle-avengers ended or how they'd come to Serra's realm, but Urza remembered what he wanted to remember and forgot the rest.
He had rescued her from the turtles. Never mind asking if he'd cared about anything beyond keeping her away from Phyrexian scrutiny. His grasp might not have been firm. He might have lost her by accident. And he had been ill ... since Phyrexia, but not before.
Xantcha was relieved to see Urza looking vigorous again, pleased to see him talking and moving in a mortal way, but she could not escape the implications of those few words: since I met you. They echoed ominously in her own thoughts. Had Urza decided something, perhaps everything, was her fault?
That warm greeting in the lower hall had been less relief or enthusiasm, than guilt.
Xantcha glanced at Serra, wondering what role she had played. Romance? That seemed unlikely with Urza ... unnecessary, too, when she could distract him with the cocoon. After she'd gotten rid of Urza's annoying, Phyrexian companion?
"You want to know what I did when you were found?" Serra asked, an indication that she was sensitive to thought and, perhaps, did not find Xantcha's mind as empty as Urza did.
"I know what you did, why did you do it? What had I done to you or your perfect realm?"
"All things, natural or artifact, are created around a single essence. Your essence is black mana. When I created my plane, I created it around white mana, because the underlying essence plays a pivotal role in determining the character of a thing. White mana is serene, harmonic. It has the constancy that allows my plane to be the safe haven I desired. Black mana is discord, suspicion, and darkness. There is black mana here-it was not possible to eliminate it entirely-but it is only the small remainder that
balances the rest-"
"I told you it is not so simple," Urza interrupted their host. "Lady Serra turned away from all that was real to make this place. She created it out of sheer will. But it seems there is a flaw, a fallacy, in willful creation. Outside, in the multiverse which is unbounded, balance simply is and all planes are balanced among all the essences. Inside, when a plane is created by an act of single will, balance is impossible. One essence must dominate and another become the odd fellow."
"I knew this place reminded me of Phyrexia!" Momentarily forgetting everything else, Xantcha savored the satisfaction of solving a thorny puzzle. "The teacher- priests said the Ineffable made Phyrexia. I thought they meant that we all answered to him, that we were all part of his plan, but it was more than that. The Ineffable created Phyrexia. It was nothing, nothing at all, before he made it."
"Precisely," Urza agreed. "I had reached the same conclusion. A created plane, cut off from the rest of the multiverse by an unfathomable chasm, no wonder it was so hard to find! But, inherently unbalanced! Think of it, Xantcha. Lady Serra retreats to her cocoon where she adds her will to her plane's flux, constantly keeping it almost in balance, but never quite and never for long. It always slips away. She prunes it to keep it small-"
"Small's never been a part of the Ineffable's plan-"
"Excuse me!" Serra said firmly and in her own language, which neither Xantcha nor Urza had been using.
The air in Xantcha's lungs became so heavy she couldn't speak and even Urza seemed to be at a loss for words.
"As I was saying." The lady's tone implied she'd tolerate no more interruptions. "The only black mana here is here because it cannot be eliminated. Nothing here has black mana as its underlying essence. Such a thing, natural or artifact, would disrupt everything around it. When the archangels found you and Urza, both near death and unable to speak for yourselves, they-I- determined that you had swallowed a piece of him. You were clinging to him. And your essence was black-is black.
"They have standing orders. Safe haven cannot be extended to anything with an underlying black mana essence. Because you had a piece of him, and we did not know then if it was a vital piece, I sent you away-put you in quarantine-while my cocoon restored Urza. His underlying essence is white mana, the same as ours. There was no risk. The cocoon purged him of a black mana curse."
The Ineffable, Xantcha thought. The Ineffable had place a spark in Urza's skull as surely as Gix had placed one in hers all those centuries ago. She said nothing, though, because Serra would object, and because she wanted to hear Urza's version of events before proposing her own.
