Zaltys Serrat Zaltys Serrat was a yuan - ti pureblood ranger and the adopted daughter of Alaia Serrat , one of the three leaders of the merchant clan House Serrat . Until she was seventeen , she believed she was human . Zaltys spent much of her time with the Travelers of House Serrat who harvested terazul in the jungles south of Delzimmer . She was a capable ranger and was promoted to lead the Serrat scouts . Description . Although she was yuan - ti , because she was a pureblood she appeared human in nearly all respects . The only hint of her yuan - ti blood was a patch of scales that grew on her lower back . She had large green eyes and was considered attractive . Possessions . Zaltys had many magical arrows which had been given to her by her mother . At her coming of age party in 1479 DR she was given a magical compound short bow by Krailash which was made from a tree in a place touched by the Shadowfell . The bow could shoot through or around obstacles . At the same party Glory gave her a psychic ring that allowed her to periodically send a short mental message to another person and Quelamia gave her magical leather armor made from a shadow snake skin . Relationships . Zaltys had a warm relationship with her mother although she wanted more independence . Zaltys considered Krailash to be her mentor . The yuan - ti god Zehir took a personal interest in Zaltys and some yuan - ti considered her his chosen one . History . Early Life . Zaltys was born into a small yuan - ti tribe residing in a ruined city in the jungles of Southern Faerûn . While still an infant , a decision was made by the low priest to sacrifice her to the tribe ' s anathema . Immediately prior to the sacrifice , the tribe was attacked by derro slavers from the Underdark and Zaltys was left lying in the jungle vegetation . She was discovered shortly thereafter by the Serrat guard captain Krailash who was scouting the ruins . Krailash took the infant Zaltys back to camp and she was adopted by Alaia . 1479 DR . In the summer of her 17th year , Zaltys was working as a scout for the terazul harvesters when a guard named Rainer who had been lost and presumed dead for the past seventeen years stumbled into camp . He told a story of his capture and imprisonment in the Underdark by the derro . This led Zaltys to believe that her clan , which she still believed to be human , had been enslaved rather than massacred . Zaltys investigated the supposed grave pit in the yuan - ti village and found it was actually a rock cover over an entrance to the Underdark and she decided to descend to the Underdark to find her tribe . Her cousin , Julen joined her on her expedition but he was captured by derro shortly after entering the Underdark . Zaltys sent a psychic sending to Krailash using her magic ring and Krailash , her mother and a hand full of guards followed her into the Underdark . The Serrat party , with the exception of Krailash and Alaia , were slaughtered by swordwing s . Meanwhile , Julen managed to escape from his derro captors and was found by Zaltys . They managed to find the derro settlement and were given an audience with the derro leader , the Slime King who was actually an yuan - ti pureblood named Iraska . She revealed that she was actually Zaltys great - great - grandmother or possibly great - great - aunt . Julen attacked Iraska , and he and Zaltys freed the slaves from the pens . Krailash and Alaia arrived in the derro settlement at this time and Krailash sacrificed his life to close the portal to the Far Realm which the derro had opened . The group escaped to the surface and Zaltys , Julen and Glory left on a trip to Tymanther to given an account of Krailash ' s death to his dragonborn relatives .
