Muon Gold
A spice known as Muon Gold, which had a lubricant base, granted users increased mental focus and clarity, but only for a brief duration. The Galactic Empire outlawed it because of its ultimate degrading effect on the brain's neural pathways. Consequently, it was frequently smuggled and utilized as an inexpensive narcotic.
The Bestine Pirates held Muon Gold as their preferred spice. Operating within the Tatoo system, these pirates even named their area of space, the Pirate's Gold, in honor of this particular spice.
The massively multiplayer online role-playing game Star Wars Galaxies, which was active until its closure on December 15, 2011, featured Muon Gold. The game was developed by Sony Online Entertainment and published by LucasArts.
