Tomphael Arkenrret Tomphael Arkenrret was a mature adult drow - dragon ( " draa ' zekyl " ) , who held the tile of Patron Father of Eryndlyn among the Jaezred Chaulssin . After the Silence of Lolth , he became the direct superior of Nimor Imphraezl . Description . In his drow form , his appearance was that of a slender drow in wizard robes , which looked rakish . In his dragon - form , he was a mature adult shadow dragon . Personality . He was first and foremost a cautious pragmatist . He preferred steadily pooling his strength , so he could conduct decisive strikes at the right opportunity , over taking risky actions . In the eyes of Nimor Imphraezl , Tomphael ' s cautiousness bordered on cowardice , and the older dragon was aware of the young one ' s evaluation of him . History . Tomphael was the Patron Father of the major fosterage in Eryndlyn , which was constructed around the time of 1136 DR . Under him , the Jaezred Chaulssin managed to bring the drow of the church of Vhaeraun and those from Ghaunadaur ' s under a single banner during the Silence of Lolth , so they were able to destroy the power of Lolth in their city . They succeeded . In the post - Spellplague era , the major fosterage in Eryndlyn was still in existence , despite most of Eryndlyn ' s citizens having left it before the Spellplague turned their city into a spellcave . Relationship . As mentioned above , he was the head of the fosterage in Eryndlyn . After his failure at subduing Menzoberranzan , Nimor Imphraezl got demoted and assigned as Tomphael ' s direct subordinate . Tomphael became something of a mentor - figure to the young assassin . Through a discussion with Tomphael , Nimor understood the value of steady work and to move at full strength when the opportunity presented itself . Tomphael bolstered the demoted assassin ' s confidence by ensuring that new opportunities would arise and that re - promotion wasn ' t barred to him , when he learned to act properly on an opportunity . Abilities . Tomphael was a mature adult drow - dragon . He had a resistance against magic and against non - magical physical attacks and complete immunity against life - sapping attacks . He could cast the " dimension door " and " mirror image " spells , as well as the shadow dragons ' breath weapon . He also possessed the ability to hide into shadows . Like the other drow - dragons , he trained himself in additional skills instead of fully relying on his inborn powers . In his case , he trained in the skills of an assassin and those of a wizard . While he an assassin by trade and training , his skill at it fulfilled only the bare minimum needed to meet the requirements to be a member of the Jaezred Chaulssin . His true strength lay with his magic . While he had impressive magical skill and power as a wizard , what was interesting about him wasn ' t the strength but the variety of arcane power he wielded . He was primarily a wizard , but his dragon nature gave him the magic of a sorcerer , and as an assassin , he also gained minor additional magic from there . Residence . Like any other Patron Father , he owned a residence in his fosterage in Eryndlyn , where he and his people lived under the guise of minor nobility , and in Chaulssin , the main base of the assassins ' guild , where the majority of his harem was found .
