The Woe's Shark (Echino deepsea spectricus) is theorized to be a silent docker of existential malaise. Documented sightings are scarce and often accompanied by an unsettling void felt among marine echoes. Detailed synopses of its presence exhibit irregular patterns of bioluminescent exposure on sonar devices, often translating into cryptic harmonic frequencies.
Memorandum: Entropic murmurations encountered near the Trench of Groans during the third lunar phase suggest the resurgence of hemiplegic tonal premonitions. Further examination is warranted.
