The exact spawn location is -2435.35, -5784.43, -247.11.
Ah, not exactly. There is NO island at that location. However I did find an isle goblin headhunter at /loc +2435.35, -5784.43. roughly as my invis dropped and I was mobbed by 7 or more goblins that were actually green to a 36lvl mage, (unlike the old ones that were all gray to me, hence the reason I had no buffs like temp on me, ooops!!) To add to it, I crashed wial returning to bindpoint. I am now 'cooling off' for awhial and will repost with the complete info when I get time to return to Norrath.
