Lorenzo's Crown

Lorenzo's Crown is an unobtainable apparel item worn by Lorenzo Cabot.

Background
Lorenzo's crown was an artifact found in Ubar, in the Empty Quarter of Arabia in 1894. Lorenzo Cabot was chief of an archaeological dig to prove the existence of ancient civilizations when he stumbled upon the artifact, rumored to be supernatural by his guide. Despite the protests of the guide, who later left the group due to the feared repercussions of disturbing the artifact, Lorenzo chose to return for it unbeknownst to the rest of his group and then returned to Boston with it in his possession.

Little did Lorenzo know, the superstitions and fear of his guide and his excavation team were well-founded; the crown, after being worn by Lorenzo, granted him supernatural powers that granted him immortality, enhanced strength and localized telekinetic abilities as well as an insatiable bloodlust. Upon discovery of these ability, his family, specifically his son Jack, had Lorenzo and the artifact locked away below Parsons State Insane Asylum.

Location
Can be found in the basement of Parsons State Insane Asylum on Lorenzo Cabot, but is unable to be acquired without the use of console commands.

Behind the scenes
The crown's use and its effects are very similar to the Ayleid Crown of Nenalata from The Elder Scroll IV: Oblivion. In both games, whoever wears the crown is presumably possessed by an unknown entity and gain powers far greater than their own.
