Demon plane of Oblivion, City of Ash
Year 192 in the Rule of the Dead
"Do we go to our death - or worse?"
Malkom Slaine gazed over at his best friend, Prince Kallen the Just, wishing he had a better answer for him, anything to ease the apprehension in Kallen's eyes.
As the vampire guards shoved them along, deeper into their stronghold, Malkom suspected death might be welcome before the night was out.
"The rumors are likely untrue," he lied, putting up a renewed resistance as the dozen guards forced them down a flight of stone steps. But his bonds were mystical; Malkom was unable to teleport or break free.
At the base of the stairs lay a subterranean chamber with an ornate throne on a dais. Though the floor was of packed earth, the walls were hung with rich silks and tapestries. Rare crystal and glass adorned the room.
At once, Malkom began analyzing every inch of the area for an escape. Ahead, a pair of winded demon slaves stood beside a freshly dug grave. More guards lined the walls, with swords at the ready. In the back, a black-robed sorcerer worked at a vial-cluttered table.
Gods, let the rumors be untrue ... those whispers of the Scarba - the abominations.
Kallen muttered, "Can you see a way out of this?"
Normally, Malkom could. Without fail, he figured his way out of seemingly impossible predicaments. "Not as of yet."
The guards shoved Kallen and Malkom to their knees before the grave.
"Ronath will pay for this once I get free," Kallen grated. Ronath the Armorer was a seasoned warrior, the strongest demon after Malkom. He'd once been Kallen's favored commander. "The traitor will not see another night."
'Twas Ronath who'd turned Malkom over to the vampires. Disastrous enough. But without Malkom's unwavering defense, Kallen's fortress had fallen just a week later. The Trothans' beloved prince had been captured.
Blinded by his hatred for Malkom - a slave turned commander - Ronath had unwittingly doomed Kallen and all the Trothans.
Malkom had already planned his own revenge. As he was neither noble nor good like Kallen, his retribution would be far more vicious than the prince could ever envision.
Without warning, a vampire traced into the room, teleporting directly onto the throne. Clad in costly silk robes, the male was pallid, his skin untouched by Oblivion's blistering sun. His eyes were wholly red, his visage twisted by madness.
The Viceroy.
When the vampires had con"uered Oblivion and turned it into a colony, they'd dispatched the Viceroy, their most malicious leader, to act as ruler of the plane.
"Ah, my two new prisoners," he said in Anglish.
Though Malkom and Kallen both were fluent in the language, they refused to speak anything other than their native Demonish - even as the use of that tongue was now punishable by death.
The vampire rubbed his narrow, clean-shaven chin. "At last, you have both been captured."
Malkom and the prince were the leaders of the rebellion, and to break them would be to break the resistance. The vampire overlords had searched for them relentlessly.
When the Viceroy snapped his fingers, the two slaves exited the room, returning moments later with an unconscious demon boy. One of their own, handed over for a vampire's refreshment. A leisurely repast.
Malkom started sweating. He strained even harder against his bonds but couldn't get free before the vampire collected the boy in his arms, then bent over his neck.
At the sight, rage spiked within Malkom. Those sucking sounds...
He bared his fangs, overwhelmed with memories of his childhood as a blood slave. His only consolation was that this boy was unconscious, a luxury he himself had never been afforded. Nor had Malkom's neck been taken, for that skin would have been readily seen - and he hadn't been kept only for his blood.
"Steady, Malkom," Kallen murmured in Demonish. "Keep your wits about you."
How many times had Kallen said those exact words? The prince has long kept me sane.
The Viceroy dropped the boy from the dais to the ground like refuse, then dabbed at his lips with a crisp handkerchief. "I confess, you two fascinate me." His red eyes burned with curiosity. "A friendship between a beloved royal and his brutal guard dog. The highest of the high, and ..." He flicked his hand at Malkom.
