Kill Terrorclaw and return to Zurjaya at Zabra'jin.
I've caught every kind of fish that lives in the marsh, but there's one that eludes me. Sure, I've caught eels and mudfin frenzies. But the last time I was out on one of the islands in Marshlight Lake, I hooked a gigantic bogstrok that snapped my line and got away.
Terrorclaw, he's called, and I won't rest until he's dead. He's too big for any fisherman to catch, so I suppose we'll just have to kill him the old-fashioned way.
