Sentient Cores are Sentient objects that can be traded in for Standing with The Quills in Cetus. Intact Sentient Cores are dropped by Eidolon Vomvalysts while Exceptional Sentient Cores are dropped by Eidolon Teralysts, Eidolon Gantulysts and Eidolon Hydrolysts on the Plains of Eidolon, one for each Teralyst Synovia that is destroyed. They appear as white and blue orbs that float above the ground, lit up by a blue aura that makes them more visible, and marked with HUD icons much like Ayatan Stars. A Flawless Sentient Core is dropped upon successfully capturing (not defeating) a Teralyst, Gantulyst, or Hydrolyst while it is tethered by the required amount of Eidolon Lures; both the Shards and the Flawless Core will be dropped by the Lures upon self-destruction, not by the Eidolon itself.
Battalysts and Conculysts on Lua can also drop Intact Sentient Cores. The Sentients aboard the Murex, either during Scarlet Spear or during Sentient Anomalies in Veil Proxima, can also drop Intact Sentient Cores. This allows for progression with the Quills outside of the Plains of Eidolon.
The Exceptional Sentient Core Conversion, a reusable Blueprint to upgrade Intact Sentient Cores to Exceptional ones, is available as an Offering from The Quills that costs 
500.
Redeeming these Cores will gain Standing with The Quills. Each Intact Core grants 100, each Exceptional Core grants 500, and each Flawless Core grants 1,200. Intact Cores are also used as sacrifices for ranking up with The Quills: 10 are required to attain the Mote title and 20 are required to attain the Observer title.
