Where's the six Gargoyle swarms?

I have been to all the islands and killed the gargoyles at each island

where Eldrig told me they were. Problem is, the quest shows that I have only completed five of the six

swarm quests. Can anyone tell me where to find the sixth swarm as I'm tired of sailing between islands

over and over again.

THIS is an medium detailed guide of the gargoyle mission,scroll down a bit and you will find the mission i dont remember the correct order but i know that you need to speak to some chars to get the swarms,also there are on the air temple map too.
