Tuir Stonebeard Tuir " Stonebeard " , Blood of Helban was a dwarf man and Deep King of the dwarven kingdom of Roldilar in the Vast in north Faerûn in the 7th century DR . History . Tuir was a descendent of Helban , whom he honored in his name . When the orc nation of Vastar , in the lands later known as the Vast , fell into civil war in the Year of Writhing Darkness , 572 DR , dwarves began to encroach from the west , spreading underground and applying increasing pressure on the orcs . Among these dwarves was Lord Tuir Stonebeard , who was determined to destroy Vastar and found his own kingdom . Working with human s and elves , the dwarves secretly developed " orcslayer " , a steel toxic to orcs . Lord Tuir Stonebeard requested over a thousand orcslayer weapons and Master Smith Fyrfar Smokebeard and High Old One Turbaern , together with the human mage Beldossan and the elven sorceress Aleratha Ilnatar worked hard over several years to forge and enchant them . Among these was the short sword " Sarghathuld " , forged in the Year of the Many Serpents , 605 DR , and given to the dwarven warrior Ulnorn . In the Year of the Spellfire , 610 DR , the invading dwarves , armed with orcslayer weapons , toppled Vastar and slew Orc - King Grimmerfang at their capital , Mount Grimmerfang . The victorious dwarves claimed the surface lands for themselves and that same year Deep King Tuir Stonebeard founded the kingdom of Roldilar , the Realm of Glimmering Swords . Tuir placed his throne deep beneath Mount Grimmerfang and held court from there . In the Year of the Costly Gift , 645 DR , the archmage Maskyr came to Mount Grimmerfang to seek audience with Deep King Tuir . He ask Tuir ' s price for a vale within the domain of Roldilar that he wished to make his home . The Roldilarren Court fell silent and Maskyr waited patiently as Tuir thought it over . Tuir did not want to yield any land to any humans and distrusted mages , but he feared the archmage ' s power . At last , Tuir offered the whole vale , from rim to rim and the earth below as deep as four men , at the cost that Maskyr pluck out his own right eye and give it to him , there and then . To the shock of all present , without hesitation , Maskyr did just that . Tuir respected Maskyr for that , having thought that no - one would do it , and kept the bargain , granting him the land . He also ordered that no dwarf trespass in the vale nor disturb the archmage . Others followed , and this marked the beginning of permanent human settlement in the Vast . Their arrival prompted King Tuir to declare that humans would be allowed to come only so far into the mountains and no further , at a point marked by the town of King ' s Reach . Roldilar enjoyed only about forty years of real peace under Deep King Tuir before it was engulfed by hordes of resurgent orcs in the the Year of the Bloody Crown , 649 DR . Tuir led the dwarven armies against those of orcs and goblins , but they were defeated at Viperstongue Ford over the River Vesper . Roldilar ' s defenses were broken , and the dwarves retreated to Mount Grimmerfang . This ended in the bloody , 20 - day - long Battle of Deepfires beneath the mountain , and the fall of Roldilar , the Realm of Glimmering Swords in 649 DR . Tuir was the last deep king whose dominion spread over the surface lands , and the last to be well known there . Personality . Tuir was stoic and grim by nature , and slow to laugh . These traits earned him the nickname " Stonebeard " . He feared and distusted mages .
