Gargauth Gargauth ( pronounced " GAR - goth " ) , or The Lord Who Watches , was the lawful evil demigod of betrayal , cruelty , political corruption and powerbrokers . He embodied the inevitable decay and corruption that accompanied all self - serving , greedy , and power - hungry leaders and groups . Gargauth held to the letter of any agreement , not the spirit , and relished betraying anyone with whom he forged a pact by twisting the contract to serve his own ends . Worshipers . The church of Gargauth was a secretive faith , although there were some significant exceptions . Description . Gargauth appeared as a fanged and clawed humanoid with horns and jagged shards of bone jutting out of his face and back . When manifesting for the first time to people , he wore an intricate guise meant to convey his handsomeness ( he rarely manifested as female ) and nobility , but couldn ' t help but revert to his true form over one to four months - however , by the time this reversion became apparent , he had usually corrupted those he appeared to so that they would not realise this - only beings who first met him after this reversion had taken place would realise that his appearance was a facade . Personality . Gargauth came off as a personable sage in most of his encounters . Regardless of the species he manifested as , people would almost always find him to be the most charming , amusing and knowledgeable being that they had ever met . Abilities . Gargauth radiated charm magic that was very difficult to resist and impossible to dispel . He was immune or resistant to most magical and physical attacks . His one weakness was being struck by silver , which had the potential to seriously injure him , though after an almost deadly encounter involving a thrown sack of silver coins , Gargauth ensured that he was protected with spells when meeting anybody he did not already have complete control over . A unique power that Gargauth possessed , which he made efforts to keep secret , was an ability to entirely absorb all the abilities of any baatezu whom he managed to completely destroy . It was this power that allowed him to achieve apotheosis . Possessions . Gargauth had access to an unlimited supply of + 3 daggers , which he could withdraw from one of his sleeves and was noted as occasionally wielding a rapier . He often carried venomous snakes wrapped around his arms , that he would use as weapons in combat . Relationships . Gargauth was opposed to many evil deities , Bane , Bhaal , Cyric , Iyachtu Xvim , Loviatar , Shar and Talona all counted themselves as Gargauth ' s foes . He posed a particular threat to Siamorphe , given his interest in corrupting those who she held up as shining paragons of virtue . Gargauth did not seek allies due to his nature as a loner , preferring to directly control minions instead . However , he could count on the support of the archdevil s of baator , including Asmodeus , who was perhaps his closest ally . Gargauth himself opposed Ghaunadaur , who stole the aspect of Gormauth Souldrinker from him . Gargauth sometimes employed a powerful blue dragon named Rathguul as a steed , whom he had dominion over due to an ancient infernal contract . History . Gargauth was once the arch - devil Gargoth whose foul nature was too much even for others of his ilk . Exiled forever from the Nine Hells to the Material Plane under pain of complete destruction , Gargauth took to wandering the planes , returning time and again to the world of Toril . The only complete record of these journeys exist in a journal he wrote while making them , the original of which is kept in Oghma ' s library . During this time , he had established a cult following on Toril and absorbed the powers and followers of Astaroth , a tanar ' ri who had become stranded on that world and later , several baatezu as well . Gargauth was ultimately responsible for the destruction of the realm of Peleveran by virtue of his manipulation of nearly two dozen powerful members of the Cult of the Dragon . He almost achieved lesser god status when his cult blossomed during the Harpstar Wars but the concerted effort of the churches of Bane , Bhaal , Loviatar and Talona crushed his followers to prevent such an occurrence . During the upheaval caused by the Spellplague , Gargauth apparently lost his divinity when he became trapped within the " Shield of the Hidden Lord " . Rumors & Legends . Despite being widely unknown to most people living in Faerûn , Gargauth appears in many cautionary tales and parables under the names of his aspects and guises . One of the most popular of these is the dwarven " Legacy of Astaroth " , which teaches dwarves that steel can be more precious than gold .
