Arantir trvia:

he send you to get Horns of Nez'ra.....

in Might And Magic there is a Necromancer named Arantir who search for a helm (with horns) to summon the lord of death(SPOIULER! that IS you Father! lol) and he is servent of asha who is a god(wait hand of chaos?)

nice little trivia

other minor thing me and a couple notice

he is last boss in "Might and magic dark messiha" but if you go assasin (stealth and dagger ) he can be downed in under 2 min (less if was for not he summon big bone dragon...avatar of death) that can be a trivia as it was a problem to the maker after release of game that not got changed and we think its kinda trivia because he got a dagger and is "rogue" like

Cant take the quest? (70 NE rogue)
Maybe i need some required rep with Ravenholdt?

This NPC has been added recently, perhaps as part of patch 2.3.

From WoWWiki:

Arantir <The Hand of Chaos> is a level 45 (elite) night elf Alliance NPC in the Lakeshire Docks, in the Redridge Mountains. He doesn't seem to serve any game purpose (yet), though Thottbot shows some abilities and a mob, Arantir's Shadow (though it doesn't show where this mob may be found, or who uses these abilities), named after him.

Seeing to the fact he is standing beside Lucius, a dwarf that plays a large role in the Alliance rogue lockpicking questline, and his rogue-like appearance, he may play a part in a future rogue quest.

There doesn't seem to be anything in the game that points at an Arantir or a "The Hand of Chaos", be that simply a title of his, or some hidden organisation he is a part of.

Edit to reply below (zomg123):
I dig and I wasn't aware of that. My question, though, comes from the fact that he was "last recorded on July 10th, 2006", which doesn't make much sense. Is it possible the NPC was in the game, removed, then re-added once again? Also, this still doesn't seem to explain his purpose.
