Angeline Fowl is Artemis' mother. Angeline knows nothing of Artemis's secret life that is filled with fairies and other magical creatures. However, when Opal wants the lemur, she makes it appear as though Angeline is sick with a rare fairy disease, making Artemis think that he gave the illness to his mother. It is just a trick and Opal is using Angeline's body. When it is over, Angeline is left with Opal's memories and knows about Artemis's secret life.
