He is for Frostfell Quest on Dec 2010 for 81th level(not for 90ish).
Location is 1350, 380, 75. Little east from Paladins of Valour camp.
I camped Playful Sea Turtles(around level 81. Can slow(partially)) at Nothern Little Island.
Pulled with Levitate from across seashore.
Sometime aggroed Fishermans(around level 79. Undead.). but their aggro radius is not wide. was easily camp with T2 Tank & Healer merc.
Wish it helps.
