Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Casca (series)
At Golgotha, Casca stabbed Jesus with his spear, in an attempt to relieve Jesus of his pain and suffering. Jesus condemned Casca by saying, "Soldier, you are content with what you are. Then that you shall remain until we meet again. As I go now to My Father, you must one day come to Me." As Jesus died, blood from his wound trickled down Casca's spear and onto his hand, and Casca unknowingly tasted it after wiping sweat from his mouth, causing his body to convulse in pain. Casca did not initially understand what was happening to him until he was condemned to work in labor mines over a 30-year period. There he slowly discovered that he does not age and cannot be killed or seriously wounded. He learned that he is immortal, although he can feel all pain inflicted on his person. While his wounds heal completely, his body accumulates countless scars over the centuries.
