Avellone said she was made to fit two of his design priorities, that is including a representative of a tiefling race and having a thief member in the player's party. Annah was both voiced by and modeled after the Scottish singer and actress Sheena Easton, whom Avellone commended for her work. Cut content from the game included a scripted plot line of Annah being kidnapped and The Nameless One embarking on, in Avellone's words, "a twisted version of 'rescue the princess' quest". As explained by character artist Eric Campanella, "Annah is very acrobatic and dexterous[,] so her outfit is light and made of leather. She has light arm and leg armor on one side which, combined with her agility, affords her better protection than full plate[,] since this would hamper her movement. The armor is also somewhat mismatched since [because] she is not particularly wealthy and probably acquired the pieces at different places and times in her life." Her design includes Wild West-style holsters on her thighs intended for quick-drawing her daggers and a spiked shoulder pad that is "probably more for ornamentation and gives off an intimidating air." To celebrate Saint Patrick's Day 2000, the developers released the "Power Action Leprechaun Annah" version (also created by Campanella) as a free DLC. When the game is played, Annah is a very useful ally due to her ability to scout ahead of the party for any potential threats and traps. She is able to deal an very high amount of damage when she performs a backstab, which can make much easier a fight against a boss or some other powerful creature. Annah is a potential love interest for The Nameless One. According to the game's vision document, "Annah has difficulties in affairs of the heart. Feelings beyond simple hostility make her terribly confused, hesitant and frustrated." If the player manages to win her affections (which "just ends in a smooch"), they are rewarded with "a slight boost to her [scoring ability]". The character of Annah-of-the-Shadows was received very positively by the media as well as the general public, having been regarded as one of the most interesting and beloved characters from "Planescape: Torment". "PC Accelerator" predicted that she would "soon take the place of Lara Croft in every adolescent RPGer's heart." Eurogamer gave Annah their Gaming Globes 2000 award in the category Female Supporting Character.
