Eurydice was a female humanoid salvage expert in the 23rd century, working for the Dark Market Syndicate in the Delta Quadrant and Andromeda Galaxy. She commanded the Spectral in the 2260s of the alternate reality.
In 2262, Eurydice was coerced into working for the Dark Market Syndicate when they took her daughter. She found the Federation starship, USS Enterprise, adrift and moving at sub-light speed. She then spoke with its captain, James T. Kirk via hologram, offering to tow them to a place where they could get dilithium. She then had her ship, the Spectral, tow the Enterprise to the Dark Market.
Eurydice then beamed Capt. Kirk over to the Spectral and then spoke to him about her reasons for helping him and his crew. After docking, Eurydice then took Capt. Kirk and his landing party to meet with a dilithium merchant, Grunthum. After making the deal, Eurydice then took them to meet the Syndicate, to get their blessing. However, Eurydice betrayed them in order to clear her debts with the Syndicate. Despite them giving her daughter back, Eurydice felt guilty for what she did to Kirk and his crew and helped them escape. (TOS - Eurydice comics: "Part 1", "Part 2", "Part 3")
