1) The mob con's oj/red to a lvl 14 toon, and starts out as neutral. 2) The Zephyr Nymphs in the area are also neutral, but do call for help. They con from green to orange to a lvl 14 toon. 3) Killing either Zephyr or the Nymphs lowers your Forest Dryads faction. Which is an Alb faction, and can not be fixed in The Hills of Claret with the other mobs. 4) It takes roughly 3 kills of these mobs to change them to agro, and that makes hunting down Zephyr a pain in the neck.
I got the Bracer of Intellect the first time I killed Zypher, and could not find a respawn in the next 90min in any of the PK lakes.
