There were two, or perhaps just one, characters named Xira Arien in the Magic storyline.
The second was an eumidian and a master assassin working for Ramses Overdark. When Overdark was ordered by Nicol Bolas to stop the uprising of the Edemi Islands he sent Xira to assassinate the leader of the rebellion, Lady Caleria. Xira was also ordered to lure Tetsuo Umezawa to Argenti, for Overdark hoped Umezawa would die fighting against the rebels, making Overdark's position stronger. Xira did this by infecting Kei Takahashi with her offspring. Xira hoped that she could use her offspring against Overdark, who kept her on a very short leash, but Tetsuo and Ayesha Tanaka killed it before it could fully develop. Kei did have to live with horrible insectoid mutations however, for which Tetsuo later tracked her down and killed her.
Most people think that these two versions of the character could be one and the same. The Xira from the second Legends Cycle was a far more experienced fighter but she didn't appear to have aged much. This could be a problem for the theory, but since next to nothing is known about eumidian physiology it could well be normal for them to live for longer than humans. Another problem is that the original Xira Arien was depicted as a human, not a eumidian. It's worth noting, however, that Xira was able to transform Kei Takahashi into a Eumidian via biological means, so it's not impossible the same was done to her human self between the events of Legends 1 and Legends 2. But this all remains theory until a future novel sorts things out. Most likely, the writers of the two books interpreted Xira's card differently, with one assuming she was an insect person, which was later supported by the change in her creature type, but the flavor text indicates she is actually just in costume.
