Jade Wind Orb

Jade Wind Orbs were items dropped from any monster in Cantha during the Dragon Festival 2006. The Jade Wind Orbs were also available as prizes on the Dragon Festival from prizes and also as rewards for the special Quests. 250 Jade Orbs granted you a Dragon Mask.

Acquisition
Also, during the special minigame after Emperor Kisu appears, each Celestial Charge delivered to an Imperial Sorcerer grants one orb.
 * Completing the 4 quests given by Imperial Guard Hanso.
 * Completing the missions given by Captain Rujiyo.
 * Competing in Dragon Nest.
 * Winning in the Dragon Arena.
 * Obtaining a Festival Prize which may contain Jade Wind Orbs.
 * Any monster killed in Cantha had a chance of dropping Jade Wind Orbs.

Because this event hasn't and isn't expected to be repeated, Jade Wind Orbs have become rare, but useless items.
