Who is Ellen Spelding in the play, Visit to a Small Planet?

Ellen is Roger's daughter, a bored college student who wishes for the opportunity to do "something important" like "save the world." She convinces Kreton to teach her how to perform some of the "tricks" with her mind that he can do, and she eventually uses these skills to contact Kreton's superior, Delton 4, and halt the war that Kreton has planned. She also focuses her romantic attentions on Conrad, a local farmer of whom her father disapproves. Ellen is the embodiment of youthful optimism and idealism. She is the only character that Vidal abstains from making look foolish.
