Where do I get/aquire the Avatars?

[Issu]

All I've seen is how to fight the Avatars, their names and abilities, and the level needed to aquire them. I have yet to find a thread, or any other piece of information on where to get them. I've looked all over google, here, and other FFXI sources. So if you can, please assist. ^^

You beat each of the prime avatars, then talk to the Taru that gave you the quest and choose to be able to summon them.

By what you've said, you already know this.

Thank you for replying, but the trouble I'm having is, where to find the NPC's that give the quests.

Look up the 'Trial By' or 'Trial Size by' quests.
