Shar didn’t start the War of Light and Darkness. Selûne did.
The Drow didn’t start the Crown Wars. The Vyshaantar clan of Sun Elves did. Unfortunately the Court of Enquiry which cleared the Drow didn’t sit until 800 years after the Drow had been forced into the Descent. The Vyshaantari got away with it for 5,500 years before eventually being punished – a feat Radovan Karadžić would no doubt love to emulate.
All completely unfair and unjust. But at least there was never any prospect of the evil megalomaniac Ivosaar Vyshaan becoming the first President of the European Union.
