Ian, Natalie, and Isabel Kabra (all from London, United Kingdom) are the richest and most ruthless team in the quest. Isabel Kabra née Vesper-Hollingsworth is the wife of Vikram Kabra, both of whom are the billionaire parents of Ian and Natalie. Ian is fourteen years old while Natalie is eleven. Both children have cinnamon-complexion skin. Ian is interested in jets while Natalie is a shopaholic. Ian also has feelings for Amy Cahill, despite the disagreement of his mother. Natalie always carries a poison dart gun with her for protection. Isabel, on the other hand, is an art dealer like her husband Vikram. She is so desperate for Clues that she is even willing to risk the lives of others, including her own children. She also killed four people; including Hope Cahill, possibly Arthur Trent, Irina Spasky, and Lester Dixon. Originally, siblings Ian and Natalie are the only ones who accepted the challenge. In the sixth book, Isabel officially joins her children due to her annoyance to them always failing to find Clues. In the end, Isabel was imprisoned for the rest of her life, and as a result of their parent's fates, Ian and Natalie are now the current leaders of the Lucians. Isabel was sentenced to life in jail with no chance of parole by Vespers due to her failing her mission. Isabel found a way back into the world her cover is AidWorksWonders. In Day of Doom, Natalie is electrocuted on the Machina Fini Mundi. Isabel sees Natalie's dead body and drinks the Master Serum, attacking Vesper One. The device then explodes, killing Isabel and Vesper One. They are all Lucians. The Kabras are deadly. Their respective cards range from No. 178 (Ian), No. 112 (Natalie), and No. 177 (Isabel).
