First of the website is very impressive. Indeed it does take quite some time to load, even after the main screen has loaded it often takes quite a while for individual pages to load.
In fact, I love the exploration point and click feeling you introduced, it fits the setting so very well. However as I said it takes some time to load the info screens of the factions but the site does not show that its loading those info boxes, it might be a good idea to show its still loading something and hasn't frozen up.
Also you might want to make the facebook and blogspot links a bit more obvious, especially the blog since that icon is not particularly well known so people don't tend to click it so much, yet you have some very interesting things up on the blog!
