About pterosaurs and other ideas: if they match PlaneShift Settings - they all can be implemented. I just afraid that your creation grows like a snowball, and soon we could be overladen by multitude of great ideas and some of them can contradict to others. It is like searching somthing in internet: you start your search, then you find some links to other interesting sites, on this sites you find another interesting links and so on... at the end you can't remember why you enter the internet

No doubt, i'm little bit overshooted with this issue, but i think there is a grain of truth in that.
I see one of the main task: explaining the existence of floating island. And as
Minetus suggested, we can refuse from this island, or make it just a huge strange Rock with a strait bottom and large top.
Minetus, i analyzed
Arangol's map (
http://img80.imageshack.us/my.php?image=map31cy.jpg)and found one important thing (imho): there are two rivers(Sitarin, Ontarvyon) flow into Port harbor (Eklato bay), but they are mostly don't seem like a rivers - they represented as a chains of lakes. Can you distinguish the river's watercourse and make lakes more detach-placed from their channel? Also, i noticed that the Diriadion lake are separated from any water source - it's unnatural.
I don't like words with such suffixes: -dion, -zion, -nion, -inuin,-anuin, -onoin, -auruin...etc. They are pronouncedly Elven words , don't disturb Tolkien's sleep
