~ 6 - 10 OI Flooding of Gler

In what can only be described as a 'daring move', Duke Dun, releasing that Gler can't be sieged because of the tunnel to Hugu, diverts the Schwirornsdt River through the tunnel, washing out a good section of walls and forcing the surrender of the city by Count Arind. Count Hugu Fonn, releasing he's on his own, declares independence.
