“Hey Dex! Your girlfriends are here, and that guy who's way cooler than you are!”
Lex, Bex, and Rex Dizznee are all Level Ones at Foxfire in the second book of the series which is Exile. Meanwhile, in the latest books, the triplets are in the middle of being a level two. This would set their ages at about twelve or thirteen. They are the subject of much controversy in the Elvin World as twins are rare and triplets are even more so. Rumours state that the triplets are a result of a bad match between Kesler (a talentless) and Juline. They are the niece and nephews of both Grady and Edaline Ruewen and Kesler’s brothers and sisters. Lex and Rex are both boys while Bex is a girl. The three of them enjoy teasing Dex, implying that he has a crush on Sophie, and love to embarrass him in front of others, like Fitz.
Lex, Bex, and Rex are troublemakers, and Dex says that they snuck into his closet and cut out the backsides to all his pants, and swung Lex off a chandelier using some ribbon.
The triplets are fraternal and are described as looking like two "mini-Dexes and a red-haired girl." They all share their fathers strawberry blonde hair, though it is described as wild. As well as this, Rex has a missing front tooth in the book Exile.
Rex's stuffed animal is Harry the Jackalope.
Lex is still learning to keep his hands to himself from girls in Lodestar
