"Arcturus" is a recurring firearm in the Final Fantasy series. It's also a significant star in ancient and modern astronomy, being the brightest star in the northern celestial hemisphere, deriving such titles as "Keeper of Heaven." The name comes from Greek mythology meaning "Protector of Arktos." It's also a name that I've been accustomed to using since the days of EQOA.

"Knightscreed" was inspired both the Wolfscreed supporting character name from Red Dead Redemption, as well as the concept of the Knights' Oath in "Kingdom of Heaven."
