Aubade

The classification Aubade, Supreme Treasures of the Netherworld is not an official grade classification of Artifacts by the Delver Guild HQ.

While Aubades are not officially recognized by Delver Guild HQ, the White Whistle Ozen has acknowledged Reg as being one.

Description
This classification sprang up from the rumor that things that threaten the value of the Abyss are kept secret or destroyed rather than auctioned off.

Trivia

 * According to Shiggy, Reg could classify as an Aubade as his body, by his estimation, seems to be a bundle of Special Grade Artifacts and might even be one of the most valuable finds in the history of the Abyss.
 * An Aubade is a morning love song (as opposed to a serenade, intended for performance in the evening), or a song or poem about lovers separating at dawn. It has also been defined as "a song or instrumental composition concerning, accompanying, or evoking daybreak".
 * Documentation of Human-looking silhouette may represent a rare instance of an Aubade being recorded by the Delver Guild HQ, knowingly or not.
