I'll give you a story I made in my head just now:Just for reference
The leader of the empire (named Douchebag) was born with the gift of Holy and Darkness, it never influenced him before but in recent years they began to corrupt his mind, leading him down the path of paranoia and anxiety.
Douchebag seeks power, the power to bring his madness to an end. His entire staff (or Nobles) have abandoned him, afraid of his darkened right eye and his brightly coloured left eye.
Douchebag experienced his first relief when a rebelious mage thought it was a wise idea to attack him.
It took him many nights to consider the reason for the relief, deciding that the magic itself was not the reason but rather, the energy that was emitted from it.
He had ordered his army to capture any and all mages they could find in the hopes it would cure him of his pain.
A few years later, Douchebag has regained his sanity, but his lust for relief has turned almost every mage in the once thriving world into a slave for his desire.
Arcana a young lass was discovered by the military using her Holy magic.
This magic (thought to be rare in this world) was just the type of energy Douchebag had been searching for.
Arcana was locked up in the cells in the royal castle awaiting direct visiting from Douchebag himself, she learns from her nearby cellmate Wallace, that he plans to harvest her magic energy to cure his own.
Wallace (who was caught stealing from the castle) ended up in the cells with his own set of lockpicks. He picked the locks for the cell and the two escaped.
Arcana left a note in her cell saying:
"You really do live up to your name, you could have simply asked the guardians to help with your problem, but apparently you really were a Douchebag".
And so they left to journey the world for some reason which I don't really want to think about yet.
Douchebag is naturally pissed off about her words and declares war on all those who use magic (Reminds me of Merlin).
Douchebag attempts to fuck with the guardians and gets his ass handed to him,
the military gets sick of his shit and leaves him.
Arcana, now a powered up magic user, kicks his arse. But his death causes Arcana to inherit his madness, just as he did when his mother died at childbirth.
