The Murex, formerly known as the Sentient Anomaly, is both a Sentient Tile Set and a Sentient warship introduced in Update 27.0 (2019-12-13) which acts as a Point of Interest and is encountered only in Veil Proxima missions on Empyrean. It is a Sentient troop transport ship notable for its alien interior and incredible size.
Murex ships are relevant to two game modes: Skirmish Railjack missions, and Murex Raid missions.
Skirmish
The Murex will occupy a node on the Veil for 30 minutes, indicated by a red flashing Script error: The function "Faction" does not exist. symbol, after which it will disappear. Another Murex will appear after a random time interval between 2 hours and 2 hours and 45 minutes.
While active, the Murex will constitute a mission objective in the Railjack mission (similar to a Pulse Turbine or Shipkiller Platform). Cephalon Cy will request that the Tenno investigate the Sentient presence in the area at the beginning of the mission. Once the Tenno enter the Murex, Cephalon Cy instructs them to "sterilize" it of Sentient life as a means to prevent Grineer exploitation. Once 20 Sentient enemies are destroyed, Cy deems the objective complete.
The Tile Set features high level Sentient enemies, and is the first area to house the Brachiolyst and Symbilyst. After killing 20 Sentient enemies in this Point of Interest, all players within the squad will receive an Anomaly Shard, which can be traded to Little Duck for the Tenebrous Ephemera and Sentient Ship Captura scenes.
Originally, destroying a red crystal within the Murex, which required the 
Paracesis, would start the Erra Quest. This is no longer accurate and the Quest can be accessed directly from the Codex upon completion of the Chimera Prologue Quest.
(unverified) Inside the Tileset also spawns Immunode which allegedly gives Sentient Immunity or prevent Secret Room from being accessed if destroyed.
Murex Raid
The Murex Raid mission has two distinct phases: transporting the OpLink Satellite and deploying Kill Codes.
The mission starts with the Railjack carrying an OpLink Satellite, which must be brought in front of the Murex. While carrying the satellite, the forward turrets are disabled, though Munitions may still be fired. Sentient Gyrix and Ionyx will attempt to destroy the satellite, along with Splintrix delivering boarding parties. The most notable of these troops is the Anu Mantalysts which will deposit Anu Interference Drones to disrupt the Railjack's systems, preventing the use of Tactical and Battle Avionics, and reduce its speed. Later in the mission, Grineer Exo fighters and crewships will spawn. Once the satellite has been delivered, it will become invulnerable and players no longer need to defend it.
The squad must then board the Murex and place their OpLinks, which will upload Kill Codes that are obtained and automatically transmitted by the Ground Assault teams. 9 Kill Codes are needed for Murex Raid players to successfully fend off a Murex ship. Sentient forces will come in waves to attempt to destroy the OpLinks.
Players may extract at any time by using the Railjack's navigation terminal. Up to a maximum of 5 Murex can be fended off in a single run. If the Satellite or all OpLinks are destroyed after fending off one Murex, players cannot continue uploading and are forced to extract.

Patch History
Hotfix 27.0.12 (2020-01-23)
- Anomaly Shards
For every Sentient Anomaly POI that you complete you’ll earn a new Anomaly Shard; a shard ripped from a Sentient Anomaly in the Veil Proxima!
- As mentioned in 27.0.11, we wanted to implement a more token based system to obtain the Tenebrous Ephemera that we removed from the drop table. An Anomaly Shard is 100% guaranteed at End of Mission for every Sentient Anomaly POI you complete.
- Little Duck + Exotic Goods
Little Duck is no stranger to Exotic goods - an Amp assembler and Toroid master, the strong and the strange are what she makes her business on. Her interest in Anomaly shards allows you to access new Exotic Goods:
- Tenebrous Ephemera
- ALL Sentient Captura Scenes
- Sentient Captura Scenes have also been removed from the drop table and will be purchasable from Little Duck exclusively.
Hotfix 27.0.11 (2020-01-16)
- Tenebrous Ephemera Removal and Future Acquisition
TEMPORARILY removed the Tenebrous Ephemera as a drop from Reinforced Sentient Containers aboard the Sentient Anomaly in Veil Proxima. The drop method is causing numerous issues in terms of connectivity stability and player frustration. We’re going to be changing the acquisition method that won’t involve a direct drop rate in a near future Hotfix/Update, and will instead be closer to a token system (complete X Anomaly missions to buy Ephemera from a vendor).
- The Tenebrous Ephemera will be coming back as soon as possible in a better acquisition method
Update 27.0 (2019-12-13)
- Introduced.
