It was originally forged during  The Thunder Forge in order for Wrathion and adventurers to further understand and wield the power of Lei Shen, using the tyrant's own power against him. After hurling the spear at Nalak, the lance reached its full potential. Wrathion then used its power to create the powerful Crown of Heaven gems.
As Wrathion and his partner sought the blessings of the August Celestials, he would use the spear against the adventurers during Yu'lon and Xuen's trials. Despite being blindfolded, Wrathion was still able to use the lance to deadly effect, being able to cleave wide deadly arcs in-front of him.
