Artist’s comment:
 
“A mysterious, shrewd Alicorn enchantress and self-proclaiming ruler of the expansive Bridlewood Forest, she leads an army of fearsome Shadow Guards to enforce her rule and enact her secretive plans to control all the magic in Equestria. Apparently, there is an item in the possession of Sunny Starscout that is key to her plans.”
 
Actually had a lot of fun with this one. I clearly wanted to go for a femme fatale look for Opaline and it was also very obvious that her dnd class should be a Sorcerer. As such, she is still the “big bad” for Dnd Gen 5, but with a bit more presence.
