WARNING! This article contains MAJOR spoilers for the recently released novel A Choice of Futures. Caution is advised.

The Elachi (also known as Gamma Vertians, Mutes and Shroomies) were an alien species native to Gamma Vertis IV, in the galaxy's Alpha or Beta Quadrants. The Elachi entered the astropolitical stage in the 22nd century and returned as a major player on the early 25th century, operating from subspace. (ENT episode: "Silent Enemy", ENT - Rise of the Federation novel: A Choice of Futures, STO mission: "Turnabout")

Biology and appearance

The Elachi are a bipedal humanoid species native to dark planet far from their class K star. They see in the infrared range. Most notably, they do not communicate with sounds. (ENT - Rise of the Federation novel: A Choice of Futures) However, they are affiliated with a solanogen-based lifeform dependent on subspace communication that appears to sound like clicking. These may be members of another species or a racial variation. (TNG episode: "Schisms") Elachi breathe a different composition of atmosphere that was noxious to typical humanoids like Humans and Romulans. (ENT - Rise of the Federation novel: A Choice of Futures; STO mission: "Turnabout")

It was revealed that the primary reason for the abduction of other species by the Elachi was that these were used as stock to grow new members of their kind. (STO mission: "Devil's Choice")


Their race claimed to serve a mysterious race of Masters and operated as part of their schemes. Individual Elachi often served superiors that were known as the First. (STO mission: "Devil's Choice")

They were shown to view other species as livestock that were required for harvesting. (STO mission: "Turnabout") The reason was because such subjects were placed in incubation rooms where they were converted into new warriors at the cost of the captive's life. (STO mission: "Devil's Choice")



One of the "Shroomies".

The Elachi evolved on the sparsely illuminated world Gamma Vertis IV. In the mid-22nd century, they sent ships to capture ships and abduct non-Vertians, whom they did not consider sentient lifeforms. (ENT - Rise of the Federation novel: A Choice of Futures) In September 2151, a vessel from this alien race pursued the crew of the NX-01 Enterprise who attempted to hail the unknown starship but did not receive any response from their hails. Each encounter with the alien vessel led to significant damage to the Earth Starfleet ship. One attack led to the race activating a dampening field on the Enterprise allowing for two of their kind to board the ship to begin invasive scans of the Starfleet crew. Captain Jonathan Archer encountered the two intruders and fired a phase pistol at them but this had no effect on the aliens who departed back for their ship. The aliens would later install a device to overload the power grid of the NX class Human ship though its crew would later use this to their advantage in penetrating their pursuers vessel. The damaged alien ship would flee after a torpedo barrage damaged it thus ending its pursuit of the Enterprise.(ENT episode: "Silent Enemy")

Amongst the Romulans, there were stories of miners that operated past the Eridan Belt who discovered alien beacons of unknown origins. Furthermore, they encountered alien beings that moved passed their outposts magnetic barriers and scan the miners before disappearing. However, little was known of these mysterious aliens except that the beacons left behind referred to them as the Elachi. Despite a Romulan presence on such worlds, the creators of the beacons never appeared and the encounters with the creatures were dismissed as paranoia. (STO mission: "A Day on the Farm")

Unknown to many, the Elachi were considered the messengers of the Iconians and claimed to hold the means to bring the ancient mysterious race. At some point, they approached Romulan officers Taris and Hakeev who were searching for the means of harnessing Iconian technology. The Elachi only spoke to Hakeev and showed him a device which they claimed was capable of bringing back the Iconians. Taris had Hakeev study the device though he claimed it was harmless leading to this incident bringing about the destruction of the Hobus star. (STO mission: "Revelation")

Legacy of Romulus

By 2409, the Romulan Star Empire had fractured following the explosion of the Hobus star which led to the destruction of the twin worlds of Romulus and Remus. In this time, the Tal Shiar rose to be a prominent force that sought the re-establishment of the Star Empire but under their rule but were opposed by the actions of D'Tan who had formed a his own government. At some point, Colonel Hakeev of the Tal Shiar forged an alliance with the Elachi to further their plans. This saw the aliens establish a beacon on the agricultural Virinat colony where it was situated inside a cavern. However, the activity of the machine and its protectors led to the native Khellid hive going aggressive which attracted the attention of the Romulan colonists. They managed to examine the alien technology but were unable to determine its purpose. (STO mission: "A Day on the Farm") During the Tapping festival, the Elachi along with their Tal Shiar allies launched a combined attack on the colony thus devastating it. The Elachi later departed though a number of colonists survived and were rescued by forces from the Romulan Republic who drove away the Tal Shiar invaders. (STO mission: "Virinat Invaded")

Following this attack, they struck at the Reman Crateris colony where they decimated the settlement alongside their Tal Shiar allies. (STO mission: "Crossroads at Crateris") Elachi technology was used to cloak Tal Shiar vessels in the Khitomer system which allowed them to sabotage the diplomatic negotiations with D'Tan of the Romulan Republic. (STO mission: "Turning Point") As part of their experiments, the Elachi began targeting ships along the Neutral Zone where the crews of such vessels and left no bodies behind on the ships. (STO mission: "Bigger Picture") They later participated on the assault on the planet Delta Corvi alongside the Tal Shiar but their invasion was stopped when Major Vrimak detonated a Thalaron radiation bomb that scorched the planet. (STO mission: "Cloak and Dagger") After the discovery of their connection to the Tal Shiar, the Elachi began increasing their raids on known space leading to the abduction of various beings. This led to an attack on the Romulan Rh'ihho Station which was repulsed by forces from the Romulan Republic. (STO mission: "Abducted")

Afterwards, the Elachi raiding forces increased the level of their attacks and harvests. This included an onslaught against the Rhi system but these were repelled by Republic forces. (STO mission: "The Best Defense") During this time, the Elachi were operating from a hidden base in the region and the Romulan Republic attempted to uncover its location. This led to them attacking one of the alien frigates designated as Target Alpha and use it to uncover the base. (STO mission: "Turnabout") This staging ground was discovered to be within subspace at a large facility called Station Alpha. Using Target Alpha, Romulan Republic personnel infiltrated the base which was sabotaged and destroyed as a result. With the help of the Klingon Empire and Starfleet, the Republic successfully defended New Romulus against the Elachi invasion fleet. (STO mission: "Devil's Choice") At Storage Facility Z98, data consoles revealed that the Iconians were the mysterious masters of the Elachi and were deploying them to deal with the various threats to their rule in the galaxy. After the activation of the Iconian Gateway at the Jouret system, an Elachi fleet was dispatched to control the gate but was destroyed by the allied forces. (STO mission: "Sphere of Influence")


Support Drone.

Analysis of their technology revealed that the Elachi made use of fungal bio-tech with trace amount of spores present from their presence. (STO mission: "A Day on the Farm")

They were noted for deploying a number of beacons for an unknown purpose. (STO mission: "A Day on the Farm") Elachi were able to use powerful passive scanning technology was that was able to disrupt enemy starship operations. (STO mission: "Turning Point")

One capability of the alien technology was the capacity to cloak entire starships from detection through the use of anomalies. (STO mission: "Turning Point") They were also able to use smaller rifts that were capable of being formed in the quarters of a humanoid and used these subspace anomalies to abduct specimens. (STO mission: "Bigger Picture") In addition, they utilized subspace as staging grounds for large bases that included Subspace Base 002 and Station Alpha. (STO mission: "Devil's Choice")

Flamethrower Crawler.

One piece of technology commonly used by the Elachi were drones that were insectile automated machines. These were capable of being deployed on guard assignments where they were at times used to protect the alien beacons from outside interference. A more aggressive use of such drones were deploying them in numbers during their attacks on enemy colonies. The drones floating nature meant that they could fly across their environment and latch on to targets whereupon the subjects were forcibly taken back to their Elachi creators. (STO mission: "Virinat, Invaded")

During their attacks, they were noted to deploy large multi-legged vehicles that were dropped onto the planetary surface whereupon they razed enemy settlements. (STO mission: "Cloak and Dagger") These large walkers were often sued in onslaughts against planets and were often supported by shuttle craft. (STO mission: "The Best Defense") Such walkers were typically constructed at their subspace bases. (STO mission: "Devil's Choice")

The Elachi were a spacefaring species able to construct large dreadnought class vessels as well as battlecruiser class ships. (STO mission: "Legacy of Romulus", STO mission: "Virinat, Invaded")
