Please Help!!!!

ok i read on wiki that: Eshau Longspear is a Paragon boss that can be found in Arkjok Ward, just outside the east exit of Yohlon Haven. i walk outside with a couple heroes ready to get rid of my crappy white non-max spear for a eshau spear but i couldn't find the boss. i then checked auctions and found that there were a few found. is anyone else not able to find the boss? Thanks!
