General resources
Breath of the Eidolon
A gas found solely on the Plains of Eidolon, refined to its purest form.
A special resource only rewarded from Plains of Eidolon bounties. Breath of the Eidolon is used in manufacturing a variety of Cetus-related items. When Breath of the Eidolon becomes trapped in molten iradite, it forms the gemstone Nyth. Vials of Breath of the Eidolon appear to be used as illumination by the Ostron, including as a component of their very common Xartaan lamps. The description of Xartaan lamps may indicate that Breath of the Eidolon glows as a result of bioluminescence1. Varzia has several vials of Breath of the Eidolon on her Foundry bench behind her. Breath of the Eidolon cannot be fed to the Helminth.
Cetus Wisp
Strange stone lifeforms that call the Plains home. They are a rare find, clustering together, floating above a patch of ground they've taken an inexplicable interest in. They are an enigma.
A special resource primarily harvested from their spawn points along the edges of bodies of water on the Plains of Eidolon. If they are approached but not collected, they will float up into the sky and disappear after a few seconds. They can also be rewarded from Cetus bounties and Ghoul bounties, or purchased from the Quills or Operational Supply.

Sentient Core (Intact, Exceptional, & Flawless)
An integral part of Vomvalysts and Teralysts, the exact function of this... device? organ? is uncertain.
Sentient cores are dropped by Sentients. Vomvalysts drop Intact Sentient cores, while Exceptional Sentient cores are dropped by the Teralyst, Gantulyst, and Hydrolyst when a synovium is broken. Flawless Sentient cores are dropped by the Teralyst, Gantulyst, and Hydrolyst when they are captured with the help of Eidolon Lures. Sentient fighters outside the Plains of Eidolon, such as Battalysts and Conculysts, will also drop Intact Sentient cores. All three grades of Sentient core have the same description. The primary purpose of Sentient cores is to redeem Standing with the Quills, but they are also used for crafting a small number of Sentient-related items. Quill Onkko sells a blueprint that converts Intact Sentient cores to Exceptional Sentient cores, thereby amplifying the amount of Quills Standing one can earn. There is no method to convert Exceptional Sentient cores into Flawless, however. Sentient cores of all grades can be fed to the Helminth to stimulate its Sentient Appetite.
Eidolon Shard (standard, Brilliant, & Radiant)
[Rare] shard gained from capturing the Sentients roaming the Plains of Eidolon. [Use it to gain Focus [or to unbind Way-bound focus nodes.]]
Eidolon shards are dropped by the large Eidolon Sentients that roam the Plains at night, with slight variations in their description based on grade. Standard Eidolon shards are dropped by the Teralyst, Gantulyst, and Hydrolyst when they are defeated, regardless of whether they are killed or captured. Brilliant Eidolon shards are dropped by the Teralyst, Gantulyst, and Hydrolyst when they are captured, and are used to summon the Gantulyst. Radiant Eidolon shards are dropped by the Gantulyst and Hydrolyst when they are captured, and are used to summon the Hydrolyst. Standard Eidolon shards are used to craft the Paracesis and to rank up with the Quills. Eidolon shards of all grades can be redeemed for Focus, and Brilliant shards are used to unbind certain Focus nodes. Standard Eidolon shards can be fed to the Helminth to stimulate its Sentient Appetite, but the higher grades cannot.
