I finished meeting up with Alex and w/ his Friends in Champa and I don..

You need to find a way to get to Lemuria... But there's heaps to do.

Explore the eastern sea. Go to all the islands in the ocean. Might I suggest heading over to Izumo, then heading to the Apogee Isles and completing the missions that await you there first. You need to acquire more psynergy, and those places are a good start.

There are other places, in eastern Osenia, that you might like to visit, such as Yallam and the Taopo swanp just south of there. Have a chat with all the poeple in Yallam...especially pay attention to the dance the kids are doing! And then further south into the cold continent of Tundaria... It might look barren, but there is something there... Just keep looking... (but only go there after going to the Apogee Isles and completing that mission.)

Once you have visited Tundaria and done what you have to do there, you will realise there is something else you can do for the Alhafrans... Go back there and help them (you will know what to do once you have done all the other stuff I said to do) then after all of that, you will probably want to re-visit Champa... Because you have something that someone there will want to see...(if you managed to not leave it behind in Tundaria... Hint... It's at the bottom of the tower... Encased in ice...) you will have to then find some other places like the one in Tundaria... They're not hard to find...

But I've given you enough hints... ;)

Have fun!
