Bersek Attacks

Berserker attacks are getting worse. These Berserkers seem be targeting the magicians who study the Merak region. I need to stop these Berserkers, but I can't cover all of Merak by myself. Every Berserker I miss means another slavering madman attacking our unsuspecting magicians. Can you help us to exterminate them? I will reward you, quite handsomely.
