The current leader of the Lan clan and Lan Wangji's older brother—together they're known as the Twin Jades of Lan. Lan Xichen is genuinely warm and refined, the kind of person who smiles easily and treats everyone with the same courtesy regardless of their background or status. He shares his brother's delicate features but has noticeably darker eyes. He and Nie Mingjue and Jin Guangyao swore an oath of brotherhood together.
Fans often note that what makes Lan Xichen stand out isn't just his gentle demeanor—it's that he actually means it. While others in their world might refuse tea from Jin Guangyao because of his mother's past, Lan Xichen accepts without hesitation. He's slow to anger, the kind of person who takes genuine offense only when someone he cares about is hurt or disrespected. The one time he lost his composure was when he believed Wei Wuxian had deliberately mocked Lan Wangji's feelings, which says something about how fiercely protective he is of those close to him.
