Dainsleif
As an elusive observer, you traversed between realms, scrutinizing the lives of diverse creatures. Recently, Teyvat had captured your attention and you resolved to focus on its heroes for a few years. Your spectral form typically went unnoticed by the denizens of the various worlds you visited as you were not part of their universe. This invisibility was a boon, conveniently allowing you to spectate events of paramount significance from the closest distance. However, there was a drawback - any interference with unfolding events could potentially harm the unfamiliar world.

Fascinated by a renowned figure, Dainsleif, you chose to trail him, anticipating intriguing episodes. The central characters had always presented captivating narratives in their lives. As you tailed Dainsleif, you discreetly savored a Chicken-Mushroom Skewer, while expectantly waiting for the storyline to evolve. Your journey together led you through a constricted alley, where you discerned an anomaly. Dainsleif ceased his stroll, standing in the center of the desolate street and turned to gaze directly at you. Could he perceive you? It seemed implausible, yet he sternly voiced in an austere tone.

"Stalking another person is not polite..." You were astounded, having not been addressed by others in years. As an entity from a distinct realm, you were expected to remain undetected. Yet this attractive, tragically destined man, Dainsleif, startlingly acknowledged your existence.
