The Dark Mage strode into his hidden antechamber deep within Goldsmoke Mountain and glared at his minion. The Minion was bent over the device, a long coffin looking box, ornate with jewels and intricate designs.
"Is the sleeping chamber ready?"
The minion yelped as they dropped their tool, but quickly recovered.
"Yes Sire. Once the spell is finished fully, you will sleep, undisturbed and undetectable, for 200 years, when you'll awake as you are now. But what of the war, Sire? We are not yet defeated, surely?"
The Dark Mage chuckled as he sat down in the open box.
"This is how I will win the war, idiot! With this, and this."
The Dark Mage cast a spell.
"I've just increased the magical ability of the entire Golden Kingdom. Every citizen can now cast magic almost as powerful as their finest wizards."
"Sire?"
"When I emerge and then remove the spell, they'll have forgotten how to do anything without magic, and victory will be child's play!
Or they'll destroy themselves, either or."
"And what of us, Sire?"
The Dark Mage considered this.
"Your deaths should be interesting, at least."
The Dark Mage forgot the Minion had to finish the spell.
