"Brunhild!" Turlogh shouted. A strange gurgle answered him. He thrust against the door. It was locked. As he heaved up his ax to hew it open, Athelstane brushed him aside and hurled his full weight against it. The panels crashed and through their ruins Athelstane plunged into the room. A roar burst from his lips. Over the Saxon's shoulder Turlogh saw a vision of delirium. Brunhild, queen of Bal-Sagoth, writhed helpless in midair, gripped by the black shadow of a nightmare. Then as the great black shape turned cold flaming eyes on them Turlogh saw it was a living creature. It stood, man-like, upon two tree-like legs, but its outline and face were not of a man, beast or devil. This, Turlogh felt, was the horror that even Gothan had hesitated to loose upon his foes; the arch-fiend that the demoniac priest had brought into life in his hidden caves of horror. What ghastly knowledge had been necessary, what hideous blending of human and bestial things with nameless shapes from outer voids of darkness?
Held like a babe in arms Brunhild writhed, eyes flaring with horror, and as the Thing took a misshapen hand from her white throat to defend itself, a scream of heart-shaking fright burst from her pale lips. Athelstane, first in the room, was ahead of the Gael. The black shape loomed over the giant Saxon, dwarfing and overshadowing him, but Athelstane, gripping the hilt with both hands, lunged upward. The great sword sank over half its length into the black body and came out crimson as the monster reeled back. A hellish pandemonium of sound burst forth, and the echoes of that hideous yell thundered through the palace and deafened the hearers. Turlogh was springing in, ax high, when the fiend dropped the girl and fled reeling across the room, vanishing in a dark opening that now gaped in the wall. Athelstane, clean berserk, plunged after it.
Turlogh made to follow, but Brunhild, reeling up, threw her white arms around him in a grip even he could hardly break. "No!" she screamed, eyes ablaze with terror. "Do not follow them into that fearful corridor! It must lead to Hell itself! The Saxon will never return! Let you not share his fate!"
"Loose me, woman!" roared Turlogh in a frenzy, striving to disengage himself without hurting her. "My comrade may be fighting for his life!"
"Wait till I summon the guard!" she cried, but Turlogh flung her from him, and as he sprang through the secret doorway, Brunhild smote on the jade gong until the palace re-echoed. A loud pounding began in the corridor and Zomar's voice shouted: "Oh, queen, are you in peril? Shall we burst the door?"
"Hasten!" she screamed, as she rushed to the outer door and flung it open.
Turlogh, leaping recklessly into the corridor, raced along in darkness for a few moments, hearing ahead of him the agonized bellowing of the wounded monster and the deep fierce shouts of the Viking. Then these noises faded away in the distance as he came into the narrow passageway faintly lighted with torches stuck into niches. Face down on the floor lay a brown man, clad in gray feathers, his skull crushed like an eggshell.
How long Turlogh O'Brien followed the dizzy windings of the shadowy corridor he never knew. Other smaller passages led off to each side but he kept to the main corridor. At last he passed under an arched doorway and came out into a strange vasty room.
Somber massive columns upheld a shadowy ceiling so high it seemed like a brooding cloud arched against a midnight sky. Turlogh saw that he was in a temple. Behind a black red-stained stone altar loomed a mighty form, sinister and abhorrent. The god Gol-goroth! Surely it must be he. But Turlogh spared only a single glance for the colossal figure that brooded there in the shadows. Before him was a strange tableau. Athelstane leaned on his great sword and gazed at the two shapes which sprawled in a red welter at his feet. Whatever foul magic had brought the Black Thing into life, it had taken but a thrust of English steel to hurl it back into a limbo from whence it came. The monster lay half-across its last victim—a gaunt white-bearded man whose eyes were starkly evil, even in death.
"Gothan!" ejaculated the startled Gael.
"Aye, the priest—I was close behind this troll or whatever it is, all the way along the corridor, but for all its size it fled like a deer. Once one in a feather mantle tried to halt it, and it smashed his skull and paused not an instant. At last we burst into this temple, I closed upon the monster's heels with my sword raised for the death-cut. But Thor's blood! When it saw the old one standing by that altar, it gave one fearful howl and tore him to pieces and died itself, all in an instant, before I could reach it and strike."
