Umbral Matrix guide
Secret rarity and a base XP of 16,000 define the Umbral Matrix, a light-absorbing module listed for Astral Observatory. The wiki gives Magnet as the bait and Night, Foggy and Autumn as its conditions, and the entry is listed as obtainable.
It weighs between 5.0 kg and 10.0 kg, averaging 7.5 kg, but the price is C$650 per kg, which yields an average sale value of C$4,875. By maximum weight it ranks 642nd of 1,059 documented fish, while by average value it jumps to 231st of 1,038, so money is where it stands out.
Astral Observatory documents 35 fish in total, and four others share the Secret rarity there: Singularity Control Unit, Stabilizer Core, Stellar Wiring and Unstable Crystal. The quote describes “A dark, light-absorbing module recovered from forbidden observatory subterranean chambers.”
Verdict: a light fish with a high price per kg and a large XP value, so its worth comes from rarity and price rather than from weight.
