Primus

Primus is a main plot piece mainly featured in RSC:Part 6 "The Fortunate Sons". Primus is the remnant of a meteor that had fallen all the way back in 1803, during the time of RSC: Part 5- where a bit of it landed somewhere in North America where it was later turned into an arrow that Muhai would later use to give herself a requiem stand. Its age as a whole is unknown but its age relative to its time spent on earth is 141 years.

Primus is said by many to be the main reason why stands appear in the 2nd universe at all. Because of its power and potential use, groups such as the Ghost Division and the Sultans of Swing have devoted their entire mission to finding it before the other group does.
