Raised by the same WeanMother as her sister XullRiia as well as living under identical conditions has made Iareanna a virtual copy of XullRiia.
In fact they both seem quite dependent on eachother and it has been noted that their performance (no matter what they are tasked with) drops makedly when separated.
Like her sister, XullRiia, she detests physical activities, being of a scholarly inclination.
