The wounded Awbee
If a group of adventurers visit Upper Blackrock Spire, they will find a small room where two orcs are hurting a small blue wyrmling. After killing these orcs and saving the wyrmling, they will be able to listen to him tell his story.
The young drake is named Awbee, and he is one of many wyrmlings stolen from their mother's clutch in far away Winterspring. The blues are not the only dragons that have been captured, however. Dragons from each flight are being captured to be used as guinea pigs in experimentation. These experiments have been orded by Nefarian, whose goal is the creation of a Chromatic Dragonflight. The chromatic dragons he has managed to produce so far hold the abilities of all five dragonflights, and have been raised to be under the control of the Black Dragons. A large number of such creatures would be unstoppable.
According to Awbee, those subjects unsuitable for experimentation are given to the sadistic minions of Nefarian and Rend Blackhand to be destroyed. The unfortunate whelplings endure horrible torture at their hands before finally dying, either from being thrown into the lava or given to the denizens of Lower Blackrock Spire to be torn apart. At the time the party finds Awbee, the orcs are getting ready to do just that.
Awbee will be grateful to those in the party, and will want to make sure that the Blue Dragonflight knows what Nefarian is up to. To this end, Awbee will give his rescuers one of his scales. If it is used in the proper place, they will be teleported to the Blue Dragonflight's matron mother, Haleh, who will be able to scry what Awbee has seen and felt when the adventurers give his scale to her.
