Aisling is the spirit of the forest who is one of the characters in Winnie the Pooh And The Secret of Kells. She is a protector of the forest, and doesn't like unwelcomed guests. At this point her age is uncertain, but she is likely to be hundreds of years old. Despite being terrified of Crom Cruach, the evil god that dwells in a cave deep within her forest, she becomes loyal to Brendan, Pooh, Ash, and their friends and does whatever she can to help them. She has many magical abilities, and often takes the form of a white wolf. By the end of the movie, she becomes the adopted daughter of Mewtwo and Good Fairy and joins Pooh and friends on their adventures. She is also Rini's best friend and will also join Serena and friends on their adventure.
