The only friend and father figure was his teacher Theevis who helped him in his attempt to flee the city and the guild . Owning no loyalty to the guild he " skimmed " money from jobs in order to buy himself a way out . The guild does not let any members leave except in death . His crew , knowing that he had taken extra coin from the jobs , sent a young man named " Losk Cale " to get the money from Vasen ' s hideout .

Thinking of the boy he saved , he named himself " Erevis Cale " being the boy ' s last name and " Erevis " meaning hunted in Thorass . Sembia : Gateway to the Realms . The Halls of Stormweather . Erevis Cale was originally trained as a thief , assassin , and linguist by the Night Masks . However , when they found out he was skimming off the top on some jobs , he fled to Sembia and joined the organization called the Night Knives , which was led by the Righteous Man , an aspiring champion of Mask , the Shadowlord . This organization placed him , at his own direction , with the wealthy mercantile Uskevren family as the head butler , a placement he created by murdering the previous butler , to be a spy for the garnering information that could be used against the Uskevren . Because of the speed and intensity with which Erevis became friends with the patriarch of the Uskevren family , Thamalon Uskevren , his loyalties split . He spent much of the decade that he worked for the Uskevren sending misinformation back to his guild and feeding them information about merchants other than the Uskevren themselves . After a decade in the service of the Uskevren , his rival in the Night Knives , Riven , secretly a Zhentarim agent , contacted him saying that their next mission would be the kidnapping of Talbot Uskevren , one of Thamalon Uskevren ' s children . Cale agreed but was adamant in not letting that happen . He laid a trap for Riven , where Cale and his halfling friend , the priest of Brandobaris the trickster and Harper agent Jak Fleet , would attack and kill those who were to attack the caravan . The decision did come hard to him because he thought he would surely be killed by his guild for his betrayal , but he need not have worried , for it was actually Riven and the Zhentarim agents at his disposal that were trying to kidnap Talbot . Erevis and Jak Fleet , after a lot of running around and evading the Zhentarim forces , which numbered many more than a usual kidnapping would entail , ended up in a confrontation with Riven himself . Riven was a better fighter than Cale and they both knew it , but the confrontation died short when an invisible Jak stabbed Riven through the back and severely wounding him . They left him to bleed in the streets as they fled from the rest of the Zhents . Surprisingly enough , Cale and Riven met shortly afterward at their usual meeting place in a tavern with Riven sporting a garish scar after being healed , and agreed to let Cale ' s protection of the Uskevren , and Riven ' s Zhentarim ties be their little secret . Shadow ' s Witness . Riven , at the direction of his Zhentarim superiors , assassinated the Righteous Man , and simultaneously released the demon Yrsillar in the process . The demon then took the Righteous Man ' s body as a vessel to operate on the Prime Material Plane to wreak havoc in Selgaunt . He transformed those in the guildhall to undead creatures called ghoul s . He attacked many noble families with the authorities not knowing what to do . He finally attacked Stormweather Towers , Erevis Cale ' s home , and ended up hurting Thazienne Uskevren , the only daughter of Thamalon Uskevren , and forcing her into a coma . Cale thought that the demon was looking for him , which indeed Yrsillar was , so thought in turn that it was his fault that this had befallen Stormweather towers . He left Stormweather in the leathers of his assassin profession to achieve what the authorities could not , defeating Yrsillar . He enlisted Jak Fleet to help him destroy Yrsillar , and the two went to the Night Knives guildhouse , Yrsillar ' s impromptu base of operations . Erevis Cale and Jak Fleet infiltrated the lightly guarded guildhouse , destroyed a number of ghouls , and then went on to destroy Yrsillar himself . Throughout Shadow ' s Witness , Cale is battling with his thoughts about being a priest of Mask . Mask contacts him several times through dreams and premonitions and eventually Cale becomes a priest of Mask , but he vows that he is his own man , and will not serve his god unless it is a benefit to himself . It ended up being for him that he did , because he likely wouldn ' t have been able to defeat Yrsillar had he not , because it was only by Mask ' s intervention that Yrsillar was banished to his home plane and effectively defeated . The Erevis Cale Trilogy . Before his new - found loyalty to Mask was formed , Erevis doubled as an assassin . The death of Thamalon marked the end of Erevis ' s service at the mansion , but not his loyalty to the rest of the family . He is especially protective of the only daughter of Thamalon ' s children , Thazienne Uskevren , with whom Erevis was once in love . Erevis was once a primary rival of Drasek Riven for the attention of the leader of their assassin ' s guild in Selgaunt . They both operated as the first and second Chosen of Mask , of which there would eventually be five , according to prophecy . They have also been referred to as the right and left hands of Mask . The Twilight War Trilogy . Erevis and Riven completed a quest to steal back a portion of their god ' s essence , which was stolen by Kesson Rel ( a former Chosen of the now deceased god Mask ) - bent on destroying all of Toril with the Shadowstorm . Kesson Rel ascended to god - like status with the divine essence stolen from Mask . while at the same time attempting to stop the take over of all of Sembia by the Shadovar . The Shadovar are a race of powerful Netherese shades who , in order to escape the destruction of Netheril shifted their whole city into the plane of shadow with the assistance of the goddess of the void , Shar . A powerful Shadovar priest of Shar by the name of Rivalen Tanthul aided in the destruction of Kesson Rel for the sake of the preservation of Sembia , which the Shadovar had interest in acquiring for themselves . Cale , Riven , and Rivalen succeeded in killing Kesson Rel , and all received equal shares of his divinity . Cale promised a portion of divine essence to both Mask and to his adventuring companion , Magadon ' s Archdevil father Mephistopheles . He made this arrangement in order to get back the missing half of Magadon ' s soul which was ripped from his friend ' s body , leaving a less human Magadon behind . Cale was killed by Mephistopheles when he made good on his promise to return the rest of Magadon ' s Soul , and thereby Mephistopheles absorbed the divine essence that Cale retrieved from Kesson Rel . Cale ' s body was frozen and placed under guard in Cania ' s frozen wastelands . The Godborn . In 1484 it was discovered that Erevis was still alive , frozen in Cania , and in order to break The Cycle of Night , he was freed from the tomb by his son Vasen Cale , who broke the icy tomb open using the sword Weaveshear . During the undoing of the Cycle , Erevis became free of Mask ' s divinity , and with Drasek Riven now the new incarnation of Mask , it is unknown if Erevis was still a cleric of the God of Thieves , or even if he counted himself among Mask ' s Chosen .
