PARIS: Apparently it wasn't always like that. According to the people that we met, before the Ferengi came, the society may have been primitive, but it was flourishing. What I'd like to know is how two Ferengi got to the Delta Quadrant.
JANEWAY: We've been looking into that. Mister Tuvok.
TUVOK: According to Starfleet computer records, approximately seven years ago, the Federation Starship Enterprise hosted negotiations for ownership of the Barzan wormhole. Included among the bidding parties were two Ferengi, minor functionaries known as Arridor and Kol.
NEELIX: And this Barzan wormhole, it's the same one we've discovered now?
KIM: Apparently, but we've confirmed what nobody knew at the time. The wormhole is fixed in the Alpha Quadrant. But in the Delta Quadrant, it jumps around. It turned out to be worthless.
TUVOK: But the Ferengi were not aware of that, and during a nefarious attempt to secure the wormhole for themselves, they were pulled into it and deposited in the Delta Quadrant.
