"You have reason to fear, Pig-Keeper," replied Achren. "Now you glimpse one of Arawn's subtlest powers. But it is a power used only when none other will serve him. Never will he leave his stronghold, save in the press of mortal danger; or, as today, when what he sought to gain far outweighed the risk." Achren's voice lowered. "Arawn has many secrets, but this one is most deeply guarded. Once he assumes a shape, his strength and skill are no greater than that of the guise he wears. Then can he be slain, like any mortal thing."
"Oh, Fflewddur, if I'd only been with you!" Eilonwy cried in despair. "Arawn wouldn't have deceived me, no matter how much he looked like Taran. Don't tell me I couldn't have told the difference between a real Assistant Pig-Keeper and a false one!"
"Foolish pride, Daughter of Angharad," Achren answered scornfully. "No eyes can see behind the mask of Arawn Death-Lord. No eyes," she added, "but mine. Do you doubt me?" Achren went on quickly, seeing Eilonwy's surprise.
The woman's ravaged features held shreds of an old pride, and her voice sharpened with haughtiness and anger.
"Long before the Sons of Don came to dwell in Prydain, long before the lords of the cantrevs swore allegiance to Math, High King, and Gwydion, his war leader, it was I who commanded obedience to my rule, I who wore the Iron Crown of Annuvin.
"Arawn was my consort, who served me and did my bidding," Achren said. "And he betrayed me." Her voice was low and harsh, and rage glittered in her eyes. "He robbed me of my throne and cast me aside. Yet his powers are no secret to me, for it was I who taught them to him. Let him cloud your sight with whatever guise he chooses. From me, never can the face of Arawn be hidden."
Gwydion stirred and groaned faintly. Taran turned again to the basin of healing herbs, while Eilonwy raised the warrior's head.
"Bear Prince Gwydion to my chamber," Dallben ordered. The enchanter's careworn face was drawn, and the lines had deepened in his withered cheeks. "Your skill has helped keep him from death," he said to Taran. "Now I must see if mine may help him to life."
Coll lifted Gwydion in his burly arms.
Achren made to follow after him. "I have little need of sleep and can best keep a vigil," Achren said. "I shall watch the night over Lord Gwydion."
"I shall watch over him," Eilonwy said, stepping to the side of Coll.
"Fear me not, Daughter of angharad," Achren said. "I bear no ill will against Lord Gwydion." She bowed deeply, half-humble and half-mocking. "The stable is my castle and the scullery my realm. I seek no other."
"Come," Dallben said, "both of you shall help me. Wait― the others. Be patient and hopeful."
Darkness had blinded the windows of the cottage. To Taran, it seemed the fire had lost its warmth and cast only cold shadows among the silent companions.
"At first I thought somehow we could overtake the Huntsmen and keep them from reaching Annuvin," Taran said at last. "But if Achren speaks truth, Arawn himself commanded them, and Gwydion's sword is already in his hands. I do not know his purpose, but I am deeply afraid."
"I can't forgive myself," Fflewddur said. "The loss is my fault. I should have seen the trap instantly."
Taran shook his head. "Arawn worked a bitter ruse on you. Gwydion himself was deceived."
"But not I!" cried the bard. "A Fflam is keen-eyed! From the first moment, I saw differences. The way he sat his steed, the way…" The harp, slung at the bard's shoulder, tensed suddenly and a string snapped with such a twang that Gurgi, crouched near the hearth, started bolt upright. Fflewddur choked and swallowed. "There it goes again," he muttered. "Will it never leave off? The slightest…ah, coloring of the facts, and the beastly strings break! Believe me, I meant no exaggeration. As I thought back it did seem that I could notice…No, the truth of it is: The guise was perfect. I could be snared again― and as easily."
"Amazing!" murmured the King of Mona, who had been watching wide-eyed. "I say, I wish I could do that sort of shape-changing myself. Unbelievable! I've always thought: How interesting to be a badger, or an ant. I should love to know how to build as well as they do. Since I've been king, I've tried to improve things here and there. I mean to put up a new seawall at Mona Haven. I've begun once already. My idea was to start from both ends at the same time and thus be done twice as quickly. I can't understand what went wrong, for I took charge of all the work myself, but somehow we didn't meet in the middle and I'll have to find a better way of going at it. Then I've planned a road to Glew's old cavern. It's an amazing place and I think the folk of Dinas Rhydnant will enjoy visiting it. Surprising how easy it is," Rhun said, beaming proudly. "The planning, at any rate. The doing, for some reason, always seems a little harder."
