Dornavver Dornavver , also known as Demonbane , was a legendary weapon of Faerûn ian history . It was a sword wielded by heroic paladins and the kings of Impiltur , and it was famous in the fight against the fiend s . Description . " Dornavver " was a bastard sword with a multicolored blade fashioned from an unknown alloy . It had a long hilt wrapped in silver wire and a silver - plated crosspiece . There was a symbol of Ilmater etched into the pommel . It weighed around 6 pounds ( 2 . 7 kilograms ) . Powers . It was a " + 3 outsider bane bastard sword " . Although it was an " outsider bane " weapon , this quality functioned only against evil - aligned outsiders , particularly demon s , rising to " + 5 " against them . In addition , when within 60 feet ( 18 meters ) of a demon , the sword glowed with a cold blue light , but otherwise had no glow . Furthermore , it could shatter a demon ' s amulet with but a touch . In addition , any demon struck by the sword would be unable to summon their kin for an hour , unless they proved particularly strong - willed . The sword increased the bearer ' s resistance to all magical effects used by demons , and granted the bearer immunity to any enchantment s or charm s they employed . In general , the wielder grew preternaturally alert to conflict and very difficult to surprise . The sword had a strong negative effect on evil creatures that held it , which could not be circumvented by any means , even magical . Previously , only fighter s and cavalier s of good nature could use it , as the hilt would fall immediately from the hands of any other who tried to hold it . Demons in particular were well aware of the notorious reputation and powers of " Dornavver " . They thoroughly hated the blade , could identify it by sight , and were likely to be intimidated in its presence . They immediately turned forever hostile against its wielder , and would inform their kin of the sword ' s owner and their location as soon as possible . History . The origins of the sword Demonbane were lost to common knowledge by the 14th century DR . In fact , " Dornavver " was forged in the Year of the Wrath Sword , 275 DR , by the master swordsmith Dornavver , for whom it was named . At the time , a plethora of evil artifacts such as Jaralth " the Fiendspike " , Kuraltaar " the Demonshield " , and Morthinmar " the Sallet of Sorrow " had been created under the reign of Qysar Shoon IV of the Shoon Imperium , so Dornavver and the Church of Ilmater created the sword in an attempt to counter these and halt the spread of evil . The sword was enchanted at Allyn ' s Anvil in the Alimir Mountains on the Feast of the Moon , 275 DR . This was the same site where the " Demonsbane " shields had been consecrated two hundred years earlier . Archsufferer Irmakul " Bloodthews " , Revered Brother Filithan , Exalted Servant Volshur the Crooked , and many other senior priests of Ilmater took part in the ritual enchantment , making impassioned prayers and howls of suffering . These events were documented in the tome " Relics of the Righteous " . After its creation , the sword was given to a paladin knighthood in service to Ilmater called the Holy Warriors of Suffering , whose fortress was on the site of Castle Dasaajk , east of the Purple Hills of Tethyr . Over a century later , one of the order took the sword to the realm of Torsil and eliminated the tyrannical Uldoon , " the Mage of Fangs " , whose armies of summoned fiend s had terrorized the surrounding lands . This feat was recorded in the ballad " Uldoon ' s Doom " , and here the sword acquired the name " Demonbane " . The paladin then traveled west of the Heartlands , bearing the sword . After this , the sword ' s whereabouts were unknown for over a hundred years . " Dornavver " turned up again during the Weeping War , now in the possession of a paladin named Sarshel Elethlim , fighting in the army of Mindal Rowanmantle to defend Myth Drannor . Wielding Demonbane , Sarshel fought in the Battle of Snowsblood Trail and the Battle of Standing Stone ' s Blood in the Year of the Firedrake , 713 DR . The only eyewitness account of this campaign was made by the War Wizard Landraul Skatterhawk , whose description of Sarshel ' s sword matched that of " Dornavver " . Some legends claimed that Captain Fflar Starbrow Melruth himself wielded Demonbane on the day of Myth Drannor ' s fall to daemon s in the Year of Doom , 714 DR , though perhaps mistakenly . Sarshel went on to use the sword in the Triad Crusade in Impiltur a decade later , and then during the Fiend Wars of 729 – 732 DR . He used " Dornavver " to destroy the " Crown of Narfell " in the Citadel of Conjurers , an act that began the retreat of Orcus ' s demon army . Sarshel was subsequently crowned King of Impiltur , and when he died , " Dornavver " was passed down from monarch to monarch as one of the royal swords . However , it was not used in battle again until the Year of the Moaning Gorge , 786 DR . The Paladin Princes , Araln , Essys , and Nord , the great - grandsons of King Sarshel , confronted Ndulu and his demon army outside the gates of the Citadel of Conjurers once again . The brothers carried the Demonsbane shields , and Nord wielded " Dornavver " in its most famous exploit . Together , they opened a vortex " portal " to force the demons back into the Abyss . Essys and Araln fell in battle , but Nord used Demonbane to slay countless glabrezu and succubi and drove the balor Ndulu and his demon horde through the " portal " , banishing them from Impiltur , and destroyed the Citadel . Demonbane truly earned its name and Nord his eternal glory . It was again used in combat in the Year of the Empty Throne , 850 DR , by King Beldred , who drove the surviving demons out of the Rawlinswood during " the Scouring " . " Dornavver " was later stored by Mage Royal Soargar in his tower in Lyrabar as part of his mission to preserve the treasures of Old Impiltur as the realm fractured . " Dornavver " was one among a hundred - or - so magical weapons in the collection known as Soargar ' s Legacy . In the Year of the Dawn Dance , 1095 DR , Soargar granted the collection to Imphras I in anticipation of when the monarchy in Impiltur would be reestablished , two years later . " Dornavver " and the rest of the weapons were shared among Imphras and his loyal battle companions , who later became his Royal Guard . It was generally accepted by historians that the sword was used by King Imbrar I in the Year of the Luminar Procession , 1127 DR , as he led the Royal Guard against the hobgoblin s of the Giantspire Mountains , but some claimed he gave it to Lord Osper Wellhaven , his general and commander of the Royal Guard . The whole force vanished without a trace . Demonbane and the other enchanted weapons of the Royal Guard were thought lost with them . Demonbane was still missing by the 1350s DR . Othiiyr Velthrann , a sage from the city of Tsurlagol in the Vast , made his life ' s work the study of the magic swords of Soargar ' s Legacy . Othiiyr dedicated himself to recording the legends around them , and pieced together the history of " Dornavver " and the other blades . Othiiyr assisted the Knights of Imphras II in their continuing quest to find the lost swords of Soargar ' s Legacy . The whereabouts of " Dornavver " remained unknown as of 1374 DR , but the Knights were working to recover it . In fact , a bastard sword known as Demonbane came to be in the possession of Jetel Xarann , a drow priestess and sword dancer of Eilistraee . She passed it on to her daughter , Cavatina , a Darksong Knight serving in Promenade of the Dark Maiden in Undermountain . In the Year of Risen Elfkin , 1375 DR , Cavatina was leading a routine patrol of Undermountain when she encountered a spellgaunt , a servant of Lolth . Cavatina slew the spider - creature ( not itself a demon ) , but not before the spellgaunt drained the magic from the sword and ultimately ruined it .
