In support of forum revitalization, I have an idea for a new plot for anypony to join in:
A powerful unicorn has made his oppressive presence known in Equestria. Called Inferno, he is a beast of fury and domination who uses dark magic to enslave and terrorize. Ill-tempered, manipulative, and cruel, he is responsible for abducting ponies from a variety of specialties and skills, forcing them to work for him in his fiery abode. His sole purpose is to gain control of others so that he may conquer Equestria and those who dare oppose him.
He has targeted unicorns, forcing them to develop a new magic spell that would render alicorns powerless. Through a manipulation spell, he plants the seed of malice in the hearts and minds of those he can tempt with power and greed. Those he cannot convince to join him are forced to endure the dungeon.
If anyone wants to get in on the villainous fun with me, Inferno could have evil henchmen (henchponies?) to help carry out his missions. This plot could give ponies something to do, if you wish to be involved (such as: as a kidnapped pony, or an OC who joins Inferno, or those who want to fight to stop him/rescue others).
I got the idea trying to think of what to do about Bright's family missing from Trottingham, but ponies from all across Equestria could be impacted by Inferno's insatiable appetite for power. Maybe they could join forces to defeat him - AND I'm fine with his eventual defeat!
Comment of PM if you want an OC involved in this plot!
