The glow merged into a shadowy form. A shape vaguely like a man it was, but misty and illusive, like a wisp of fog, that grew more tangible as it approached, but never fully material. A face looked at them, a pair of luminous great eyes, that seemed to hold all the tortures of a million centuries. There was no menace in that face, with its dim, worn features, but only a great pity—and that face—that face——
"Almighty gods!" breathed Kull, an icy hand at his soul; "Eallal, king of Valusia, who died a thousand years ago!"
Brule shrank back as far as he could, his narrow eyes widened in a blaze of pure horror, the sword shaking in his grip, unnerved for the first time that weird night. Erect and defiant stood Kull, instinctively holding his useless sword at the ready; flesh a-crawl, hair a-prickle, yet still a king of kings, as ready to challenge the powers of the unknown dead as the powers of the living.
The phantom came straight on, giving them no heed; Kull shrank back as it passed them, feeling an icy breath like a breeze from the arctic snow. Straight on went the shape with slow, silent footsteps, as if the chains of all the ages were upon those vague feet; vanishing about a bend of the corridor.
"Valka!" muttered the Pict, wiping the cold beads from his brow; "that was no man! That was a ghost!"
"Aye!" Kull shook his head wonderingly. "Did you not recognize the face? That was Eallal, who reigned in Valusia a thousand years ago and who was found hideously murdered in his throneroom—the room now known as the Accursed Room. Have you not seen his statue in the Fame Room of Kings?"
"Yes, I remember the tale now. Gods, Kull! that is another sign of the frightful and foul power of the snake priests—that king was slain by snake-people and thus his soul became their slave, to do their bidding throughout eternity! For the sages have ever maintained that if a man is slain by a snake-man his ghost becomes their slave."
A shudder shook Kull's gigantic frame. "Valka! But what a fate! Hark ye"—his fingers closed upon Brule's sinewy arm like steel—"hark ye! If I am wounded unto death by these foul monsters, swear that ye will smite your sword through my breast lest my soul be enslaved."
"I swear," answered Brule, his fierce eyes lighting. "And do ye the same by me, Kull."
Their strong right hands met in a silent sealing of their bloody bargain.
