foes…and there were more than a few…were not in the habit of watching for an invisible foe who also glided from shadow to shadow with the stealth of a master assassin。 Nimor was more concerned with the various magical barriers shielding the house。 He habitually protected himself with spells designed to counter and confuse various forms of magical detection； but they were not foolproof。
Green and gold radiance glimmered around him as he crept along the steep； tiled roof of a square tower。 The Faen Tlabbar； like many other Houses； used magic to illuminate and decorate the baroque spires and balconies of their home。 Nimor lowered himself to his belly and edged down even farther； headfirst； listening carefully。 Below him he expected to find a guard post； and an entrance leading into the manor itself。 Over the decades the Jaezred Chaulssin had used magic to scry what they could of the layout and defenses of many great Houses in more than one drow city； and the slender assassin had carefully studied his brotherhood's notes and drawings on House Tlabbar。 The information was； of course； inplete and out of date； as parts of the castle were blocked from all scrying； and the Jaezred Chaulssin had not studied the Houses of Menzoberranzan in a very long time。 Nimor would have preferred to update his information through the bribery or capture of a Tlabbar guard； but he simply did not have the time to arrange such a thing and keep the rest of his timetable intact。
He heard the soft sounds of movement on the balcony below the eave of the roof he lay on。 Two； he guessed； at least one wearing chain mail。 He would have to be swift…a single outcry could spell the end of his single…handed assault on the castle。 With calculating patience； Nimor edged out even more and found himself looking down on a curving gallery beneath the overhanging eave。 To his left； the walkway became a walled stair leading down to the lower battlements； while to his right it simply ended at a black doorway。 The door itself stood open。 Directly beneath him stood a drow male in armor； gazing out over a lower courtyard。
Nimor studied the fellow for a full thirty heartbeats； planning his strike as he quietly slipped his dagger from its sheath。 It was a blade of green…black enchanted steel that glistened wetly in the glimmering faerielight。 Then； still invisible； he rolled himself off the roof and dropped down behind the Tlabbar guard。
The assassin's feet thudded softly to the flagstones。 The guard started to turn and opened his mouth to cry out； but with one remorseless movement； Nimor clapped a hand over the fellow's face and punched his dagger deep into the base of the skull。 The blade grated on bone； and the Tlabbar guard simply sagged into Nimor's arms； dead on his feet。
Nimor let the nerveless body slump to the floor and looked up at the other sentry in the guard post； a fellow in the black robes of a wizard。 The Tlabbar mage glanced over at the rustle of sound； just in time to see his watch mate fold up and collapse for no apparent cause…for Nimor was still invisible。
〃Zilzmaer？〃 he said sharply。 〃What is it？〃
Nimor bounded forward and rammed his bloody knife up under the wizard's chin； nailing his jaws closed and transfixing the Tlabbar's brain。 The mage jerked two or three times； violently； then shuddered and died。
〃Shh；〃 the assassin hissed。 〃It's nothing。 Go to sleep。〃
He laid the wizard alongside his panion； and turned to the dark archway leading into the castle proper。
Knife in hand； he stalked through…only to be halted by an invisible； intangible barrier that blocked the archway as surely as a wall of masonry。 Nimor frowned； summoned up his willpower； and tried the archway again； only to find his passage barred in mid…step。
〃Damnation；〃 he muttered。 〃A forbidding。〃
The Tlabbar castle； or its interior anyway； was warded by a great fixed spell that utterly prevented an enemy from setting foot within。 Nimor could elude or undo some magical traps； but the forbidding was simply beyond his ability to penetrate。
That explains the open door； he thought。 The Tlabbars are confident in their magical defenses。 Now what？
Nimor sheathed his knife and studied the archway。 A spell of forbidding could be crafted to defend a building or area in one of several ways； but if the Tlabbars wanted to move about their own castle； they would have had to make a forbidding through which one could pass without too much difficulty…perhaps with a token of some kind； or maybe with a password。 Nimor quickly searched the bodies of the two Tlabbar guards he'd slain； but found nothing that seemed like it might serve as a token to pass the forbidding。
It might be anything； he thought。 A cloak clasp； an enchanted coin in a purse； an earring or a necklace 。 。 。
He decided he didn't have time to experiment。 With one hand he picked up the dead wizard and tucked the fellow under his arm； then he strode back to the archway and steeled himself to step through。 This time； he passed through without resistance； as if the ward was simply gone。
Something the Tlabbar guards wear； then； Nimor decided。
He briefly considered shouldering the dead wizard and carrying the fellow along in case he needed to pass another warding inside the castle； but decided against it。 Stealth and speed were his best defenses； and lugging a corpse through the castle was not particularly subtle。 Besides； the Tlabbars were not likely to have two forbiddings in their palace； or to use the same key for both if they did。 He unceremoniously dumped the wizard on the other side of the doorway； and headed inside。
The archway opened into a long； high…ceilinged corridor that ran above one of the Tlabbar halls。 Doors made of pale zurkhwood lined the hall； opening into studies； parlors； trophy rooms； and other such chambers if Nimor's old maps were correct。 He ignored them all and darted swiftly down the hall； reaching a small staircase at the end that descended to the level below。 Here he encountered a magical glyph barring passage on the stair； but he sensed the trap before stepping close enough to trigger it。 He simply vaulted over the rail instead； dropping lightly to the stairs below。 The stairs swept around in a grand curve and led him to another gleaming black corridor near the center of the Tlabbar castle； leading to the House shrine。 The floor was polished black marble that would have gleamed like a mirror had there been any light to see by。 Not far ahead； a pair of House guards stood watch over a great double door leading into Lolth's sanctuary。
Nimor smiled invisibly and congratulated himself on his timing。 The matron mother； and perhaps a daughter or two； would be within； performing some empty ritual to their mute goddess。
Carefully staying out of sight； Nimor took one more look around to make sure no one else was approaching。 He studied the two guards outside the door。 They seemed no more than young officers； proudly attired for their exalted duty as guards to the matron mother； but Nimor did not trust his eyes。 The two were more than they seemed； he was certain of it。 He decided to bypass them if he could。
Gathering himself； Nimor raised his left hand； on which gleamed a ring as black as jet。 The ring of shadows was perhaps his most useful weapon； a device that conferred a number of useful magical powers。 He called upon one of those powers； and melted into the shadows of the black corridor only to step out on the far side of the shrine's door； into House Tlabbar's most sacred sanctum。
The temple almost filled the central floor of the great palace； its graceful dome rising overhead； chased in silver and jet with Lolth's spider insignia。 The shrine was lit with a sinister silvery radiance； the better to display the lavish wealth House Faen Tlabbar had expended in decorating the Spider Queen's chapel。 Nimor spared no admiration on the gold baubles and gem…encrusted images； though。
Matron Mother Ghenni and two of her daughters abased themselves before the towering black idol of the silent goddess； groveling before Lolth； no doubt beseeching the Spider Queen to restore her favor to
