Drowning

Drowning was a Chord as part of a Psalm that also included Laconia. It was killed during the Union War, but lives on as a 'living ghost' of its former self. Drowning is known to be able to communicate telepathically across vast distances, and is able to impart not only the sound of a bell tolling in one's head, but the deafening, rattling feeling as well. It's also capable of imbuing other creatures with the ability to flash freeze and shatter certain objects, as it did to Symbol in Nacrine Tide 07 — Sunflare Pt. 3.

Drowning isn't known to speak, but was able to impart the impression that it's called Drowning to Symbol when she made telepathic contact with it in said session. It was also able to impart the feeling of crushing pressure and biting cold, as if being at the depth of the sea. Its appearance and location are currently unknown.
