"Why, by all the bloodiest gods, must I always endure such fools around me?"

A bolt of magic streaked from Sirana's fingertips. It ricocheted wildly around her circular spellcasting chamber, deep in the subterranean warrens of the thieves' guild, pulverizing priceless sculptures and blasting antique furniture to ashes before finally dissipating against the porphyry walls.

"How could they lose?" Sirana shrieked, her hands clenched into fists. But no human being could answer her. The last three thieves who had entered her chamber were now scuttling around the floor in the form of cockroaches, doing their best to avoid being crushed by her boot heels. "How could they have lost to a band of doddering holy men? All that blasted abishai had to do was bring back an old book and a foolish boy!"

Sirana caught a glimpse of her reflection in a mirror of polished bronze. She liked what she saw-a tall, shapely woman with dark hair and smoldering eyes, clad in a thin white shift belted by a heavy braid of gold. Yes, she thought, even in her rage she looked supremely beautiful. She enjoyed this human form she had taken. Not a hint of her fiendish heritage showed beneath the sultry, feminine exterior.

She sank into an ornately carved chair-one of the few items in the room that had escaped her magical wrath- and bit delicately on a knuckle. It was time to put rage aside and calculate a new course of action. Revenge was best planned with a cool head. Sirana knew that well. After all, she had made revenge her specialty.

It was obvious that a direct attack on the clerics of Tyr would not avail her. She had spent months taking over Phlan's thieves' guild, perverting it to suit her purposes. Then she had summoned Slayer to be her servant. Slayer was a baatezu abishai, a magical creature of fearsome power, but he had failed miserably. No matter the armored horde of thieves and the pack of feral spinagons she had sent to help him.

She picked up a small black-lacquered box from a table beside the chair. It was her most precious possession, a gift from her beloved mother on the day Sirana had murdered the old crone. It was a box full of magical memories. Carefully, Sirana opened the lid. Gradually an image began to form in the darkness within.

An image of a lofty tower, hewn of crimson stone.

Though Sirana had never gazed upon the tower with her own eyes, it was nonetheless a familiar sight to her. The tower had belonged to her father, Lord Marcus, a powerful Red Wizard from the eastern land of Thay. Once it had been a citadel of awesome power built above a legendary pool of darkness. Marcus had managed to imprison the entire city of Phlan in a cavern underneath the tower, intending to drain the life-forces of the citizens in order to transform himself into a demigod.

"But it was all for nothing," Sirana whispered mournfully. "If only I could have been there to help."

She watched as history replayed in the images of the black box. She saw the defilers come to the tower: a ranger, a sorceress, a barbarian who could assume the form of a great cat, and finally the one who always sent a shiver of fear through her-a skeletal paladin, his empty eye sockets glowing with horrible, holy blue light. The undead paladin had been the cause of her father's demise, and for that she despised him most of all. The paladin had turned to dust at the end of the battle, so he was beyond the reach of revenge. But the others were not.

She watched as the tiny tower inside the black box began to topple and fall. She watched as the invaders fled the scene of destruction. For long moments, the images were still. Nothing moved. Then Sirana could glimpse her mother, the beautiful, fiendish erinyes who had served the human, Lord Marcus, crawl from the ruins, bleeding, wings twisted and broken, yet alive.

The erinyes had given birth to Sirana not long after the defeat at the red tower. Because of her half-fiendish blood, Sirana had grown quickly. Early on, her mother had sown the seeds of enmity in Sirana's heart, teaching her everything about the powers of darkness that might be useful one day to hunt those who had killed Marcus and injured the erinyes. When Sirana was nine, she had tested her daughter's progress in a magical duel. In the course of the battle, Sirana had slain her mother, gaining the erinyes's power for her own. Neither regretted the outcome of the duel. Even as she lay dying, the erinyes had presented the memory box to Sirana and made her take a vow of vengeance.

For years, Sirana had bided her time, waiting for the perfect moment to enact her revenge. And then a wondrous opportunity had presented itself. She discovered a fantastic new source of power that made her stronger than she had ever dared to hope. A plan unfurled in her mind. Not only would she kill those who had slain her father, she would also regain the precious Hammer of Tyr the city held so dear. Without the hammer, Phlan would never be healed of the vice and corruption that had come to plague it since the hammer was lost. Then she would ransom the hammer to one of the many dark gods who despised Tyr. In exchange for the relic, she would demand to become a demigod, just as Marcus himself, her father, had once dreamed. Her vengeance, and her destiny, would be complete.

The iron door of her spellcasting chamber flew open with a boom, shattering her pleasant reverie. She scowled, snapping shut the memory box. A cruel light shone in her dark eyes. Yes, she would have her revenge, and she would become a deity. This minor setback at the temple meant nothing at all. But first she had some tedious business to take care of.

"We have dealt the imbecile clerics of Tyr a blow they will not soon forget, Sirana!" a voice thundered.

Slayer. The abishai strutted into her chamber, displaying dagger-sharp fangs. Several roaches scuttled about in terror. Unlike Slayer, they possessed an inkling of what was going to happen.

The massive fiend stood before Sirana's chair, breath reeking, the veins in its membranous wings pulsing with black blood.

"It was a glorious battle," Slayer snarled arrogantly. "The morons of Tyr will never stand another assault."

"Is that so?" Sirana crooned. "And what do we have left to assault them with, Slayer? An army of cockroaches?" She flung a small crimson ball of energy at one of the insects crawling by. When the smoke cleared, all that remained was a scorched spot on the stone floor.

Slayer shrugged massive shoulders. "They couldn't prove any worse in battle than your spinagons, mistress. Not that your army of thieves was much better. Despite their ineptitude, I almost got my hands on The Oracle of Strife. Then a blasted paladin I had set ablaze had the gall to collapse on the book. It was ashes before I could blink. Your idiot spinagons should have stopped him, but they had all perished at the hands of an elven illusionist." The fiend's scarlet eyes glowed hotly. "You didn't tell me there would be a mage in the temple, mistress. Tch, tch! You should be grateful I am still alive to serve you."

A smile coiled itself about Sirana's lips like a small ruby serpent. "Indeed, abishai, I am exceedingly grateful. And I feel I should grant you a reward for your accomplishments."

She lifted a hand. Slayer's eyes flared suspiciously. Black flames encircled the fiend's body. Layer after layer of magical protections wove themselves about the abishai. The fiend glared at its mistress smugly. It had nothing to fear from the half-breed daughter of a lowly erinyes.

"You dare to raise a hand against me?" Slayer snarled. Drool flew from the abishai's maw, pitting the stone floor where it splattered. "I am a prince among fiends. Your mother's kind are insects to me, and your father's most powerful spells could not so much have scratched my defenses. You summoned me into this world, Sirana, but do not for a moment believe that you will be able to hurt me."
