Lan Wangji

Lán Wàngjī (蓝忘机) was born as a young master of the Gusu Lan sect, was later on given the title The Nephrite (which is a type of jade) and eventually joined Wei Wuxian's Imperial Harem.

Personality
Lan Wangji was raised to value rules and discipline above anything else yet he does not blindly follow them and instead questions which rules he should follow at all times and which rules deserve to be broken sometimes.

He is fiercely loyal and protective of his loved ones but sometimes has trouble expressing his feelings through words, so he tries showing them through gestures instead.
