Background / History

Su Yun first traveled through Teyvat as the Fourth Descender, taking the Traveler’s place and completing that journey. He arrived on Douluo Continent a week before the story begins. The academy system gave him Divine Official-level Soul Power and a beginner’s card draw that brought companions from Teyvat to the newly appeared Teyvat Academy near the Star Dou Forest 1.

As headmaster, Su Yun recruits students and uses system rewards to bring more people from Teyvat. Zhu Zhuqing becomes the academy’s first student; her enrollment earns him five Intertwined Fates. His larger aim is to move Teyvat’s people beyond the Abyss’s encroachment 5 10 11 27.

He also oversees the academy’s practical growth. He approves Ningguang’s plan to adopt and train orphans, sends staff out to publicize the school, and worries that its supply of dependable teachers will not meet demand. The Faction Rankings eventually place Teyvat Academy first, drawing applicants from across Douluo Continent 10 11 32 50 52.

Appearance

Su Yun has a handsome, unusually youthful face: observers in Heaven Dou City take him for someone around seventeen or eighteen, despite the power he displays 17 33.

• Wears an Anemo Vision at his waist, which glimmers when he uses its power 17.
• Is recognizable from the portrait shown during the Sky Screen’s introduction of Teyvat Academy 33.

Personality

Su Yun is playful with his companions but attentive to their needs. He indulges Columbina’s wish to compete at the Great Soul Arena, coaxes the overworked Jean into taking afternoon tea, and often mediates between Columbina and Sandrone 10 21 24. He also looks after their safety: when nobles harass the two women in Heaven Dou City, he confronts them and later refuses the Crown Prince’s demand that he apologize 17 20.

His confidence does not prevent him from worrying about the academy’s finances, staffing, or Teyvat’s future. He is especially concerned with bringing people away from the Abyss, and is openly relieved when he reunites with Paimon after crossing worlds 4 11 27 32 41.

• Immobilizes the Titled Douluo Dugu Bo before he can act 20.
