Lulu

Lulu is a hollyphant, a celestial being from the upper heavenly realms of the Outer Planes. Despite the size difference, Sylvira Savikas is convinced Lulu may have been present at the original Charge of the Hellriders; however, Lulu does not have any memories of such, having woken up in the red sands of Avernus and engaging in a number of hijinks and adventures before hitching a ride in someone's bag and ending up in the Prime Material Plane.

She instinctively teleported some folks out of Elturel just before it vanished (proving Nora Baert and Alyssa Krol weren't hallucinating after all), but Lulu doesn't know how she knew to do this.

On opening the infernal puzzlebox and hearing the infernal contract within read aloud, she recovered a core memory and announced suddenly that Zariel was the name of her angel.
