There's an NPC by the name of Kera stuck under some rocks (21975/27268 almost on the dot) on the Floating Island. (who i can assume to be a bloodmage trainer by the fact she's a bloodmage and she does not beleive a dragon can be of any assistance to her.)
Also, the textures for the water falling off the two smaller floating islands does not reach the water on the 'main' floating island. Similarly, the water flowing off the 'main' floating island, it's texture does not reach the lake below it.
And the portal does not have any destinations (though i suspect this may not be a bug.)
