Lucinda

Lucinda was the name that Ensign Hector Arroyo gave to the energy-based entity he encountered inside a wormhole while testing a prototype wormhole drive ship. It had never encountered any other beings before and was very curious about Arroyo. Over time, the two grew close together to the point of merging into a single being that called itself The One. Curious to explore the universe Arroyo came from, The One returned the prototype ship to normal space, at which point Lucinda and Arroyo were ripped apart. Lucinda was reduced to a ten centimeter wide orb, but quickly grew when it drained energy from the wormhole ship. Lucinda decided to feed on the entire universe, frightening Arroyo, who used the ship's shields and wormhole generator to send Lucinda back where it came from. Instead, Lucinda ended up passing all the way through the wormhole into the Delta Quadrant, where it began heading back to Arroyo.

Four years later, Lucinda encountered the Tyvek and completely drained it of power, killing most of the crew in the process. The energy from the ship allowed Lucinda to grow to 100 kilometers wide. The USS Anomaly was sent to rescue the Tyvek's command crew and later caught up to Lucinda. The entity attempted to drain the ship. Arroyo was the Anomaly's helm officer and stole a raceabout to draw Lucinda away. Commander Prosak followed him aboard to get an explanation. Arroyo apologized to Prosak for what he had to do and blew up the raceabout just as Lucinda surrounded it. Lucinda saved Arroyo and Prosak, taking over Prosak in hopes that Arroyo would join with Lucinda in the human way. Arroyo refused at first but eventually gave in as he admitted that he only felt fulfilled as part of The One. Lucinda returned to the Anomaly to continue draining it, but the Anomaly crew sent the ship wildly careening through different dimensions, causing Lucinda terrible agony. Arroyo convinced Lucinda to take them to Bain, so he could convince Bain to stop and settle things peacefully. Lucinda sent them both to the Anomaly's bridge, where Arroyo was able to explain everything to Bain. Bain ordered the ship back to normal space, and Arroyo rejoined with Lucinda, giving up his physical body. Merged again as The One, Lucinda and Arroyo left to explore the universe.
