A crowded marketplace in the Delphic Expanse where Archer goes in search of a formula for synthesising trellium-D and comes away with Rajiin, a slave who is secretly spying for the Xindi.
The floating bazaar is visited in Rajiin. Needing trellium-D to shield Enterprise against the Expanse's spatial anomalies, Archer, Tucker and Reed go there to find someone who can tell them how to make it. A chemist named B'Rat Ud sells them the formula, taking payment in spices from Chef's galley, which are a rare luxury in the region.
In the same market a trader in women, Zjod, offers Archer his merchandise. One of the women, Rajiin, breaks away and begs Archer for protection, and he takes her back to the ship.
The escape is a ruse. Rajiin has been sent by the Xindi-Reptilians to gather biometric data on humans for a bioweapon, and she scans several of the crew before she is caught.
