Calispar Delgorth Calispar Delgorth was a human man and a priest of Talona in the late 1360s DR . He was a member of first the Red Brigade mercenaries and later the Vipers bandits . History . For some years , Calispar lived in the city of Procampur in the Vast , where he operated a secret workshop and experimented with and sold poison s and venom s . Eventually he was discovered by priests of Torm , who ran him out of town early in the Year of the Shield , 1367 DR . Afterwards , he fell in with a mercenary force , the Red Brigade , where his priestly magic and other skills came in handy . Captain Cedric Ravajar included the priest in all of the company ' s decisions , and the two men became firm allies , perhaps even friends . In the Year of the Banner , 1368 DR , two Brigade scouts reported a dead - magic zone in Brynwood Forest . Cedric kept the find secret , telling only Calispar , and the two scouts disappeared shortly afterwards . Later that year , Cedric announced his retirement and disbanded the Red Brigade . Calispar and a trusted few departed with Cedric and returned to the dead - magic zone , where they reformed into the Vipers , a bandit group . They built their base , the Vipers ' Nest , within the dead - magic zone , and began raiding merchant caravans going through the Glorming Pass . Calispar became a senior member of the Vipers . Calispar had a special laboratory built at the Vipers ' Nest where he continued his research . He soon found that plant - based toxins grown within the dead - magic zone were unaffected by magic , and theorized that they had absorbed the essence of the zone . He immediately saw the potential of poisons completely immune to magic . Therefore , he contacted the Shadowkind assassin s , and offered his magic - resistant poison in exchange for the deaths of a few of his enemies , including the high priest of Torm in Procampur . The Shadowkind accepted on the condition of proof of the poison ' s magic immunity . Calispar accepted and organized a demonstration in the nearby hamlet of Sevenecho . Autton Shadowshroud was sent to oversee the test , and met with Calispar near Brynwood on the 28th Eleasis in the Year of the Gauntlet , 1369 DR , before being taken to the Vipers ' Nest . Though Calispar took precautions to safeguard the hideout ' s location , such as blindfolding Autton and ensuring he was alone , the priest forgot to conceal his trail , allowing the ranger Dura Gerathu to track them . After Cedric spotted Dura on the 29th , he sent Calispar and a force of Vipers to attack and kill the ranger in his cabin in Dura ' s Vale . On the 1st of Eleint , Calispar and Autton slipped into Sevenecho to poison a well , killing a few villagers and sickening more . The priests of Tymora found that their magic could do nothing to identify or cure the poison . The experiment a success , Calispar and Autton returned to the Viper ' s Nest to concoct more of the magic - resistant poison . However , Calispar could not make it lethal enough for the Shadowkind ' s purposes . Therefore he worked long and hard under Autton ' s gaze over the next few days to refine a more potent version . Personality . Calispar was obsessed with completing his magic - resistant poison and his deal with the Shadowkind and thus getting revenge upon his enemies . Abilities . Calispar Delgorth was a priest of Talona , possessing the skills and powers of a malagent . Among his spell s , Calispar could cast the Talonite spell " poison touch " . He was skilled in the fields of herbalism and alchemy . Description . He was 6 feet and 1 inch ( 1 . 8 meters ) tall and weighed 200 pounds ( 90 kilograms ) . As a Talontar , Calispar ' s face was tattooed with black and blue whirling designs upon his cheeks and brow . His black hair was poorly and closely cut , and his eyes were black and beady . Possessions . In combat , Calispar wore chainmail and fought with a footman ' s mace or a Talonan ceremonial poisoned dagger . He also possessed " incense of meditation " and " glasses of comprehending languages and reading magic " . At the Vipers ' Nest , he owned a collection of books on herbalism and alchemy , and kept a planter ' s box of various toxic flora , and used alchemical equipment to brew and distill his poisons . Calispar owned a journal bound in green dragon hide which detailed his experiments with poisons , among them his magic - resistant poison . With this information , a reader could manufacture many kinds of poisons and their antidotes . However , Calispar wrote it all in Dethek script to make it harder for others to learn and steal his secrets .
