Waervaerendor Waervaerendor , nicknamed by himself the Rapacious Raider , was the shadow of one of the most famous black dragon s in Faerûn . Personality . Waervaerendor shared an unusually powerful empathic link with his twin Voaraghamanthar . They truly acted as one soul in two bodies and their greatest fear was that someone would discover their secret . From a young age , Voaraghamanthar and his twin desired immortality but they were not interested in the normal dracolich transformation . However , they believed that Chardansearavitriol ' s condition was somehow different and tried to replicate it . Both dragons were able sorcerers . Waervaerendor liked face - to - face discussions with others . They saw most other creatures only as food or annoyances to be quickly disposed of . The exceptions were adventurers and other dragons . They avoided other dragons , not out of fear but in order to avoid being discovered as twins . Adventurers , on the other hand , they viewed as tools too useful to be killed and the Black Brothers needed to recover too many artifacts to not use adventurers that agreed to work for them . Activities . The Black Brothers patrolled their domain efficiently . If they detected other dragons , they retreated underwater to avoid conflict , unless the visiting dragons were trying to settle in the mere . In that case , they fought to the death to kill the intruders and keep their secret . If they detected adventurers , Waervaerendor would spy on the group to see if they could be useful for the brothers . Usually , he appeared to scare the party , before calling himself by his brother ' s name and proposing a deal . He could detect all tricks or attempts to deceive him . If negotiations failed , Waervaerendor briefly attacked before proposing a deal again . If negotiations failed again , Voaraghamanthar intervened and the Black Brothers killed the adventurers . History . Waervaerendor and his twin Voaraghamanthar hatched in the Mhair Jungles , and thanks to their empathic link they managed not to kill each other before hatching . On the contrary , they killed all their other siblings and fled before their parents came back . After wandering Faerun for a time , they finally found a home in the Mere of Dead Men , attracted by the isolation of the place and legends about the hoard of Chardansearavitriol and the treasures of flooded Uthtower and other realms . They especially hoped to find the lost " Twin Crowns of Myrmoran " , reputed to have enhanced the empathic bond between the fraternal monarchs of Uthtower and Yarlith and granted them magical powers . They started posing as only one dragon , named Voaraghamanthar , and soon tales were told across the Realms about the legendary Wyrm of the Mere , a strange black dragon that could appear out of nowhere to assault adventurers . Despite not being really interested in becoming dracolich es , they approached the local Cult of the Dragon cell to use them for their plans . Thanks to the cultists , the Black Brothers recovered one of the " Twin Crowns of Myrmoran " . In 1372 DR , they captured a Helm ite adventuring party and planned to use them to search for the " Twinned Crown of Uthtower " , the second of the " Twin Crowns of Myrmoran " . With both crowns , Voaraghamanthar and his twin hoped to increase their powers .
