Kayla was originally from Neopia Central, but traveled through a time portal into Meridell's history. There, Kayla runs the Magic Shop in Meridell Castle, where she makes magical potions and sells them. In the Meridell-Darigan wars, she masterminded the transformation of a group of Turtums into giants, an equal match for Kass' war machines. When Lisha and her friends role play, Kayla always pretends to be Kauvara, her role model.
A few of my giant Turtums have mysteriously shrunk back to normal size, and they ran off to play a game of bullseye before I could catch them. Humour them for a bit, while I try to see where my potion went wrong.
