Field record

It appears in the charts only as a long, slow shadow crossing sonar at the very edge of range, logged under the same name by three separate expeditions in a row without any of them agreeing on what they actually saw. The one thing every account shares is the direction it was heading: down.

Marginal note: “every sighting agrees it was heading down”

Habitat

ZoneThe Lower Dark

Depth range2,100–2,800 m

DiscoveryFound only in full darkness, well below where sunlight reaches — real depth, no lamp of your own to help you spot it first.

Catching it

A Abyssal-tier catch needs at least a Heavy-Gauge Net— anything under that rating can never hold it, whatever the throw. Bought at the Quartermaster’s counter for 850 crystals. A held net inks this entry for good and pays its ledger bonus on the spot.
