Eris (2370).
Eris is a Vorta operative in service of the Dominion. She was involved in an attempt to infiltrate the Federation in late 2370. She is the only Vorta known to possess telekinetic abilities.
While Benjamin Sisko and Quark were on a camping trip in the Gamma Quadrant with Jake Sisko and Nog, Eris appeared at the campsite posing as a refugee from the Dominion. The three of them were then captured by the Jem'Hadar, allowing Eris to gain Sisko's trust. Eris was apparently fitted with a telekinetic suppression collar, and she helped them escape after Quark unlocked the device.
However, Quark later discovered that the collar was nothing more than a complex locking mechanism (When he was attempting to strip it and sell the plans for profit, naturally), and that Eris could have helped them at any time. Her true mission exposed, Eris escaped from Deep Space 9 via transporter. (DS9: "The Jem'Hadar")

- Eris is the name of the ancient Greek goddess of strife and discord, who, in anger at being denied a place at the wedding of Thetis, threw a golden apple among the chief goddesses, which set them arguing amongst themselves as to who was the most beautiful, which ultimately led to the Trojan War. Eris's role in the episode is analogous to a "golden apple"; an agent sent into the Alpha Quadrant to sow strife and discord.
- Eris was played by Molly Hagan. Producers intended to bring back Eris in "The Search, Part II" and "The Ship", but the actress was unavailable both times.
