Story
From the brief times that the group has observed her, very little information is learned but some small tidbits are evident. Her boss is confident delegating almost any task to her, including an important first meeting with a foreign sovereign and managing the defenses of major cities. Second, she has a pretty good grasp of business and trade affairs. Third, she keeps her distances from both the events and the sexual debauchery around her.

She has a brief appearance at the end of the Chapter 3, when she is spying on the Fucklord and his pet in The Tower. The scene is ambiguous enough that it's unclear is that is her only goal, but strongly hints that both Incubus Kings are aware of the existence of other realms and that they visit them. The goals of that visits are unknown for the moment, but there are tensions between them (she describes the Fucklord as an annoyance and she is looking for something/someone that gets rid of him).

She also observes Simon and the party during their first expedition into the Tower, expressing her concern over Simon's potential to take unexplained "final steps" very quickly.

During chapter 4, after evaluating the player's Headquarters defenses, she describes herself as "a demon hybrid, built from one of Philon's citizens and many other components" and notes she uses her body to maintain the Anak's shard (meaning sexual activity between them). She also spies on the party during their invasion of Erosia, but may be identified and negotiated into stopping.

In Chapter 5, at the end of the 2nd Gathering, the Anak instructs her to fight to the death against overwhelming foes, seeming to abandon her. Instead, she helps Simon's group destroy the Lustlord by suppressing his regeneration, then joins Simon at his Headquarters (but not his harem) when it is apparent the Anak has barred her from returning to Philon.
