Foundry:The Hundredth (ST-HSGEQZ7BS)

"The Hundredth" (mission ID: ST-HSGEQZ7BS) is a standalone Foundry mission for Starfleet characters. (There is also a version for Klingon Defense Force characters, titled "Wa'vatlhDIch (The Hundredth)"; aside from some dialogue differences throughout, the two versions are essentially identical. Both are also suitable for allied Romulan Republic characters.)

As of 26 January 2018, both the Starfleet and KDF versions of "The Hundredth" are Foundry Spotlight missions, the first by their author to have that honor bestowed upon them by Cryptic Studios. These are also the first STO Foundry missions set in the Delta Quadrant to be spotlighted by Cryptic.

Historical context
This mission takes place in the year 2410, between the Cryptic-authored story arcs Future Proof and New Frontiers.

Plot summary
The player is contacted by Lt. Cmdr. Kyla VanZyl from the Delta Quadrant. On behalf of Rear Admiral Tuvok, she asks the player to investigate a disturbing incident reported by the Turei. One of their patrol craft encountered a large fleet of unidentified warships passing through the Underspace without authorization. Being in no position to challenge such a mighty force, the patrol craft instead discreetly followed them through the subspace tunnel network to determine their destination, which turned out to be the Kemari system, near an Underspace terminus 93 light years from Turei. Their purpose is unknown, but apparently has something to do with the "Gamechanger", a mysterious and highly prized creature being hunted by the Hirogen in that region of space.

The player's ship is confronted by Hirogen almost immediately upon her arrival in the Kemari system - but then, almost as suddenly, unexpected assistance arrives in the form of a small fleet of Dominion warships, which turn out to be part of a much larger task force sent in search of a lost Founder - one of the so-called scattered across the galaxy from the Founders' then-homeworld centuries earlier - whom the player quickly realizes must be the "Gamechanger".

According to the Vorta mission commander Eraun, this Founder's travel pod had found its way into an Underspace terminus in Gamma Quadrant and drifted through the network before emerging in the Kemari system, but had already left long before the task force arrived. Hoping to get the Dominion on their way home without causing any more trouble in Delta Quadrant, the player agrees to assist in the Dominion's search. Eraun transfers to a Jem'Hadar Attack Ship to shadow the player's ship while the Jem'Hadar's primary handler Loriss takes the rest of the fleet to resume the search elsewhere.

The player's first destination is Prelnar V, a planet the Voth have been stripping bare for some unspecified scientific research, and the Changeling's last known location according to Eraun. The player's team transports to the surface and meets with the ranking Jem'Hadar officer, First Jikar'iklan, to develop a mission plan: The Jem'Hadar will scout ahead and engage any Voth they encounter while the player scans various locations in the area for Changeling lifesigns. Eventually the player's team does locate the apparent source of the lifesigns, but it is merely residual; the Changeling has already been here and gone. A group of Hirogen hunters is here, however, and some of them attack the player while others engage the Voth and the Jem'Hadar. The player must return to the beam-down coordinates and defeat the survivors of a large Hirogen vs. Voth engagement before they and the Jem'Hadar can safely return to their respective ships.

Meanwhile the ship has picked up communications from the Hirogen saying that the "Gamechanger" is on the move, specifically toward the nearby Gor Iven Nebula, within which sensors are nearly useless due to the nebula's ambient radiation. Both Eraun's and the player's ship set course, and must use a sort of echolocation to find the nebula's only solid body, a rogue planet that turns out to be Class M but assimilated by the Borg. The player intends to proceed with caution, but that goes out the airlock when Eraun begins transporting Jem'Hadar search parties to the surface.

Beaming down after the Jem'Hadar, the player watches them get into a firefight with Borg drones on the surface - but the "drones" turn out to actually be members of the Borg Cooperative, who are staging their own raid on the planet, in order to upload a viral agent designed to disrupt the neural subspace links of the planet's drones to the Collective, thereby freeing them. One of the Cooperative raiders is actually a Jem'Hadar himself, named Kudal'akar, who is surprised to see his own kind again. With his help, the away team and the Cooperative arrange a cease-fire and temporary alliance with the Jem'Hadar against their common enemy, the Borg Collective. Together they launch an assault on the Collective's compound, where the player's science officer picks up a morphogenic signature - a telltale sign that a Changeling is near.

Inside the compound, the Cooperative raiders upload their viral agent while the player's team resumes their search for the Changeling, both fighting Collective drones along the way. Finally, in one of the side corridors, the team finds the Changeling as one of three captive specimens being studied by the Borg. They release the Changeling, who then takes humanoid form and says her name is Irla. Before they can escape the compound, a Hirogen hunting party confronts the player and demand Irla be turned over to them. But Irla has already used her shapeshifting ability to slip past the Hirogen and join a group of Jem'Hadar reinforcements. Together with the Cooperative forces and the player's team, they defeat the Hirogen and secure Irla, though Kudal'akar is killed during the battle - which then continues in orbit until the Hirogen and Borg Collective forces are destroyed.

On the way back to Turei, however, a disagreement brews between Eraun and the player. Irla is reluctant to rejoin the in the Gamma Quadrant and wishes to accompany the player back to their side of the galaxy; Eraun insists that she will need Jem'Hadar protection if she does so, which the player says is unacceptable - so instead, the player proposes an alternative solution.

Flash forward two weeks: Eraun, Loriss and Irla have reconvened with the player aboard the Jenolan Dyson Sphere. Soon they are joined by a familiar and smartly dressed figure: Odo, the former Constable of Deep Space Nine and another of The Hundred. At his invitation, she takes his hands and they briefly Link. In that exchange, Irla begins to understand her true nature.

Star Trek canon references

 * : This mission contains numerous callbacks to events and characters from throughout the TV series. Here is a partial list:
 * "": Odo recalls having arrested Nog for burglarizing DS9's on the day Starfleet arrived, and says he's impressed at how far Nog has come since then.
 * "": Both the Jem'Hadar "Victory Is Life" speech on the Borg planet and the Ketracel White ceremony aboard the Dyson Sphere are taken from this episode.
 * "": Upon realizing the Changeling is no longer on Prelnar V, one of the bridge officers notes that Laas first appeared to Starfleet as a cosmozoan lifeform, suggesting that this one could also have taken cosmozoan form in order to escape the planet.
 * "": Just before Odo rejoins the Great Link, he changes "clothes" into a tuxedo for Kira. He sports a similar outfit for his cameo in this episode.

STO content references

 * Cardassian Struggle mission arc: Vorta characters Eraun and Loriss were both introduced in "The 2800" portion of this arc, and return for "The Hundredth". In addition, both Neman and Laas (both from the earlier, rewritten portion of this arc) are mentioned in passing.
 * The Delta Quadrant mission arc: The author's original intent was to incorporate numerous factions introduced in STO's Delta Rising expansion, in order to explore the fallout from this arc's events. To simplify the story, only the Turei and the Borg Cooperative were directly used, although the Vaadwaur are mentioned in dialogue and three pre-existing Delta Quadrant factions - the Hirogen, the Voth and the Borg Collective - are also featured.
 * "Time and Tide": At one point during the final scene, Eraun mentions having met a Vorta claiming to be a temporal agent from the future - an implicit reference to the Dominion's signing of the Temporal Accords. This agent may or may not be the Vorta character the player meets during "Time and Tide".
 * The original Path to 2409 chronology published by Cryptic during the run-up to STO's launch revealed that Kira Nerys is now the Kai of Bajor - hence Odo's mention of this during his cameo. (At the time this mission was published, Kai Kira had yet to directly appear in STO.)
