See also: Rani's House.
Rani is a water-talent fairy that can do "amazing, magical things with water:" bounce it like a ball, mold it into the shape of a fish, scoop it up in her fingers without losing a drop, or even making music/sound with water. She can also help her fellow fairies with water-related things, such as getting water to boil faster. Being a water fairy, Rani cries easily because of the extra amount of water in her, and is considered by her friends as the most passionate of them all. This also influenced her passion for water, and her desire to get involved with it, loving rainy days, splashing in puddles, and swimming, even in her favorite dreams. 
Gail Carson Levine Trilogy
In Fairy Dust and the Quest for the Egg (2005), Rani is chosen as the head of the team to save Mother Dove's broken egg, along with Prilla and Vidia. In other for the dragon Kyto to fix the egg, he demanded three items: Captain Hook's double cigar holder, a golden feather from the golden hawk, and a mermaid's comb. To get the last item, Rani asked Prilla to cut off her wings so she could swim to the mermaids. Rani felt no pain because fairies wings are not sensitive, like hair. As soon as Prilla finished, Rani's wings crystallized. Reaching the dragon's Kyto lair, they realized they had lost the golden feather, so Rani gave her crystallized wings instead. From there on, Brother Dove became her assistant, and whenever she needs him, Rani whistles and Brother Dove flies to her side and carries her, and even though she misses being able to fly on her own, Rani is not entirely unhappy about losing her wings, since she had always longed to swim.
In Fairy Haven and the Quest for the Wand (2007), the Never Mermaids started making the water level higher until they got what they wanted in exchange for the mermaid comb (given to Kyto previously). Rani, Tinker Bell and Queen Clarion went on the quest to get the Fairy Haven's wand. In possession of the wand, Rani's first wish was to make the mermaid Soop like her, the second to have wings that could work underwater. She grew scaly fish-like wings and gave the wand to Soop, who began singing, accidentally turning Rani to turn into a Never Bat.
Rani retained her fairy conscience, yet she lost control of her body, following the never bat's instinct. She flew away and behaved like a regular never bat, to her chagrin. When Beck, Prilla, and the Golden Hawk found her, they helped Rani regain control of her body. But now her bat-self was trapped in her consciousness. In the end, when Rani got the wand back, her bat conscience wanted to be free, but Rani remembered her promise with Mother Dove about the dangers of wishes. All wishes were reversed. She lost her friendship with Soop and turned back into her fairy form. Her bat-self remained, now sharing her mind as a small subtle consciousness as a logical, overly polite mind, along with her water fairy's emotional passionate personality.
In Fairies and the Quest for Never Land (2010), Rani helped finding a way to dose Kyto with water birds. Along other water-talent fairies Rani went on the quest keeping Kyto at bay. Rani cried about the other fairies that had died because of Kyto. When her bat conscience called Gwendolyn "esteemed," Rani apologized and told Gwendolyn about Rani-bat.
