SandWing treasure
The SandWing Treasure was stolen by three scavengers and Blister right after Queen Oasis' death, about twenty years before the events in the series. Known artifacts include the Lazulite Dragon, the Eye of Onyx, the SandWing Scepter, and one of the three existing dreamvisitors.
The treasure was one of the main reasons why the dragon tribes were fighting in the war; the SandWing queen being the other reason. The Eye of Onyx was the most sought after, as whoever held it was the SandWing queen. The IceWings spent a lot of their time searching and destroying Scavenger Dens; thus it can be concluded that finding the stolen treasure was a priority to Queen Glacier.
It is unknown if the treasure was returned to he SandWing treasury after Blister's death. The Eye of Onyx was hidden in Queen Oasis's skull by Smolder's pet Scavenger, Flower, since it seemed too dangerous to keep around. Two scavengers, Holler and Fluffy, had the Lazulite Dragon and the dreamvistor, which was returned to Sunny.
