—Sothis talking to Byleth
Sothis first appears before Byleth in a dream, asking for their name and birthdate. By sheer coincidence, the two share the same birthday. However, she quickly falls back asleep and the dream ends.
Shortly after this dream, Byleth alongside their father Jeralt are asked by some young students to help them repel some bandits. While most are dispatched, the leader, Kostas manages to ambush Edelgard and Byleth leaps between the two. Just as Kostas's axe is about to strike Byleth, time suddenly stops as Sothis uses her power to freeze time. She berates Byleth for their recklessness but is suddenly shocked by the fact that she is now able to remember her name. Pondering Byleth's fate, the two realize that Sothis not only can pause time, but also rewind it, granting Byleth a second chance to redo their rescue, this time disabling Kostas. Sothis continues with Byleth, speaking directly to them telepathically, unseen by the rest of the world.
Using her power to rewind time, Sothis saved Byleth's life from bandits. She does not physically appear, appearing only inside Byleth's mind, so nobody except them knows of her existence. She grants Byleth the ability to use her time manipulation power called Divine Pulse. Sothis seems to have lost all recollection of her past, but does remember calling the Red Canyon home.

It is eventually revealed that Sothis is the ghost of the Goddess, after her death at the hands of Nemesis. Byleth is her reincarnation—which is why they can communicate with her and share the same birthdate—though Sothis comes to regard herself and Byleth as separate individuals, as they do not share personality traits or memories. Rather, if Sothis desires it, she could destroy Byleth's personality and transform them into a new body for herself. She is the mother of Seiros, and it is Seiros' intention for Byleth to be subsumed by Sothis in order to undo her murder, which Sothis flatly refuses to do as it would simply be another murder for her own sake.
In order to escape Solon's trap, Sothis completely merges with Byleth to grant them her power, and disappears as a result. Byleth's appearance changes as a result, and remains that way in all routes except for the Crimson Flower (Edelgard's) route, where Sothis' Crest Stone—implanted in Byleth's stillborn heart—is destroyed following Rhea's demise. Byleth's link with Sothis is severed and they return to their original appearance, though in return, their heart starts to beat for the first time and their life is spared.
Despite her youthful appearance, Sothis speaks and acts as though she were a grandmother. She is frustrated at her inability to recall her past. In the times she is awake, she offers commentary and questions the state of things, providing advice to Byleth on how to proceed. However, despite being a passenger within Byleth, she sees herself as above them, and sharply admonishes them when they respond to her with comments she deems foolish.
