Arcybite is a mineral that is highly prized by the Ferengi for commercial purposes.
In 2369, Nava completed his takeover of the arcybite mines in the Clarus system, a fact that was recognized and applauded by Grand Nagus Zek at a meeting on Deep Space 9. (DS9 episode: "The Nagus")
In 2373, Quark attempted to obtain an arcybite contract with Alraki warlords. (DS9 short story: "... Loved I Not Honor More")
Later in 2373, arcybite ore futures were continuing to rise as they had been doing for some time. (DS9 episode: "Ferengi Love Songs")
