The Last Black Dragon

I dont know 100% of the lore surrounding the black dragons in Warcraft. If I'm correct there are still black dragons in outland... my question is would Wrathion try to kill my black dragon pet (or mount) if he saw it?? Maybe ill just hide my pet... and never mention I helped out the red dragon flight in making his egg.... =I

BTW my Alex sculpt is finished!! Pic's will be up later!
