Let me start by saying hi and that I hope that everyone's week has been well. Happy Friday! I'm new here, this is my first idea and please keep in mind that it is still just that. Down to business, here it is.
SCP-XXXX: The Holy Lance (Spear of Longinus, Holy Roman Spear, etc.)
The Spear itself is sapient, and it chooses people to wield it. It first appears in the historic record in the hands of a Roman soldier, referenced in the Bible and other texts considered reputable. The soldier (Longinus, St. Longinus) is aging, going blind and present at the crucifixion of Christ. After Jesus dies on the cross, Longinus is ordered to pierce his side, and does so with the Lance. At this time "water" and the blood of Christ pours out, some landing on the Lance itself, some getting into Longinus' eyes. This heals his sight, and from there he professes faith in Christ saying "In truth this man was son of God".
The Lance then is believed to have fallen into an organization known as the [REDACTED], from the 1st Century until the time of a man known as Charlemagne. Founder of the Carolingian Empire (and widely recognized as first in the line of the Holy Roman Emperors), and next known wielder of the Lance since Longinus. From here the Lance supposedly remained in the possession of the HREs until a time when that nation collapsed, and once again the spear more or less drops from official record, supposedly in custody of the Papacy (more to come here, i.e. The Crusades, persecution of various groups, etc.)
Enter Hitler. The Lance, using its mental influence, chooses Hitler to wield it. This causes his intense obsession with any and all things occult, which makes him begin to accrue items of this nature, all in guise for his want of the Lance. Upon obtaining it the Lance influences him on his path of world domination, and when it ultimately fails the Lance falls back on its original plan to reinsert itself into the Papacy. It chooses General Patton temporarily, as a stepping stone back into Papal custody. This plan is successful, but at this point the Foundation becomes aware of the spear and it's anomalous properties through various agents implanted in the former Nazi regime (close to Hitler one would presume), such as Patton, who was himself a Foundation agent.
The Foundation obtains custody of the spear, and institutes containment procedures. Of course this needs fleshing out, and I haven't gotten the full extent of the idea down here, but I just wanted to bounce it off of all of you to see what is thought of it before I started a rough draft. Of course I'm open to any and all critique/suggestions/etc. Thanks in advance for the input!
