Many years later, she wakes up to the hell that is the Equestrian Wasteland. Desperate to reunite with her friends and safe her home, she goes in search of the scattered remains of the Tree of Harmony's physical elements. Along the way, she befriends an injured dog (Dogmeat), and learns to fend for herself.
After Starlight finds the six physical elements, she ponders what to do next before finding a holotape, one about Twilight recording everything she knows about the Elements of Harmony. According to Twilight, the physical elements will glow if their bearers are still alive, which ultimately shatters Starlight. Her friends promised to always be there for her, they promised that they would come back to her. And even despite having the comfort of Dogmeat, her sorrow is too much for her to handle.
The physical elements are dark, no glow present at all.
