Ivala

Though obviously an important person, present in the prologue montage and the banner used on the game's various websites, this mysterious woman was not explicitly named in dialogue until the end of Chapter 4. She appears to be the namesake of the Church of Ivala, though it seems clear she is not so all-seeing or all-powerful as the Church proclaims.

Story
She is first shown in the cutscenes after the Prologue, wordlessly watching the world from an isolated mountain peak.

Her next appearance is in another cutscene, between Chapters 2 and 3. Her mountaintop is surprisingly visited by another being, the winged Mithyn, who addresses her as "sister". Their conversation is emotional and full of cryptic references. At least, it reveals that she is a captive and Mithyn is unable to free her, and they also mention having an older sister (who "doesn't care"). The other topics are less clear. Mithyn is concerned about the fate of one Zelica, who apparently has been captured by a "monster". The Tower features prominently in the conversation. Both are anxious about the place and mention an old man who has looked inside it and has been broken by the knowledge (the full details seem to fit what was revealed about King Alonon during the Ardford summit). Before bidding a tearful farewell, Mithyn expresses puzzlement about the faith Ivala puts in "that meaningless man". (Could this be Simon?)

In the cutscene between Chapters 4 and 5, she meets Tanurak and they insult each other, claiming each is a minor obstacle to the other's plans.

Near the beginning of Chapter 5, a spoken message reaches the ears of Ivalans across Arclent, but Simon's inner circle believe it to be an impersonator.

At the end of the Incubus Incubus War Aftermath, she is freed from her prison and her captor is revealed.
