Also referred to as the Northern Spear, this is the signature weapon of the Pei family and represents Tianyao's strength. It is the sole inheritance of Lady Yingwu, daughter of Pei Hao. The spear currently stands displayed in Tianyao, guarded day and night. The Pei Army elevated the Northern Spear just as the Blood Whip of Wanyue had helped forge the Pei Army. Pei Nai took up the Northern Spear and donned battle armor, becoming a commander.
