There were six wizards still engaged in the committee besides Simon, and when they collectively decided to go after him, he was determined to put up a strong fight against them. After all, hadn't he been reflecting their powers back and forth during this whole silly ritual? Stolen indeed.
Simon wielded a magick mirror to great effect as you attempted to annihilate him - fireballs reflected back at the wielders, who's own shields would drain from the backblast of power. Crystals of ice ricocheted around the room, and gusts of wind turned aside before they could reach the madman.
Simon - call him simple, would you? How complex to replace the Bursar so elegantly, to mimic the madman that no one paid heed to any longer? Simon turned to Ridcully, ready to unleash his own powers of corruption upon the Archchancellor. His mirror seemed to grow larger and larger as it absorbed more of your spells, until it seemed ready to burst.
Simon had inherited power from his line - a magic mirror, a book detailing how to corrupt the ritual, and magical acumen aplenty. But the one thing that he didn't seem to inherit was his grandfather's old adagae.
"No matter how subtle the wizard, a knife in the shoulder blades will seriously cramp his style."
Ponder Stibbons shakily stepped away as he mumbled the old UU motto, amazed at the blood on his own hands.
"I have made some inquires, and Hex tells me that one of Simon's cohorts yet remains. Find him, and finish this."
Everyone knew what would happen that night. They weren't sure who it would happen to, but they knew that vengeance was coming. It was time to end this, before more of you ended up like RaveBomb did.
simple_simon - Simon Cardigan (leader of the Corrupted Wizards) - lynched
Your grandfather passed down a text to you about the Renewing Ritual, and you know that it will be possible to corrupt the elements and use them to overcome the other wizards. You are the leader of the Corrupt Wizards.
Your great-grandfather passed down a magic mirror, which can reflect elements and elemental powers on to another. You can use this once per night to reflect both any words sent to you to another target, but also any power usage that takes place at night.
