The Biggest of Them All

Objectives
Slay Mragesh and return to Zurjaya in Zabra'jin.
 * Mragesh slain
 * Potion of Water Breathing (provided)

Description
You've dealt with most of the little hydra, but I doubt Mragesh was impressed by your display. He's a cunning, ferocious beast and he's dogged many an angler in his time.

I intend to be the last one he'll ever bother. He's bound to be hiding deep in the waters of Serpent Lake, to the northeast. He's a has-been; he just doesn't know it yet.

Rewards
You will also receive:
 * 10750 XP (or at level 70)
 * +250 reputation with Darkspear Trolls
 * +250 reputation with Darkspear Trolls

Progress
Have you "retired" old Mragesh?

Completion
I'm sure the old boy must've seen his days coming to an end. With all these new arrivals, the old order couldn't stand. It's just as well his spirit is at rest now.

Progression

 * 1) Angling to Beat the Competition
