SandWing treasure
The SandWing Treasure was stolen by scavengers and Blister right after Queen Oasis' death, about twenty years before the events of the series. Known artifacts from the collection include the Lazulite Dragon, the Eye of Onyx, the SandWing Scepter, and one of the three existing dreamvisitors.
The treasure is the main reason why the dragon tribes are fighting in the war; the SandWing queen being another reason. The Eye of Onyx is the most sought after, as it determines the SandWing queen. The IceWings spent a lot of their time searching and destroying scavenger dens; thus it can be inferred that finding the stolen treasure was a priority to Queen Glacier.
It is unknown if the treasure was returned to the SandWing treasury after Blister's death. The Eye of Onyx was in Queen Oasis's skull and the scavengers, Fluffy and Holler, that Sunny encountered in the Brightest Night, had the Lazulite dragon and the dreamvistor.
