Once the undead have been handled, the Prince decides it's best to evacuate the area since they're likely to return in greater force. You do a few side quests to round up everyone into town, then are sent up a large hill to Greymane Manor, which was previously unreachable due to being blocked by a gate. You speak with King Greymane and he arranges for caravans to transport everyone.
Now clearly the people of Gilneas haven't had quite enough misfortune yet, so while going down a hill the whole lot of them crash. You have to help gather everyone again, then you walk to another nearby town on the edge of a forest that looks like an improved version of Duskwood. Through more questing you venture into the forest, help unite everyone in deciding to retake Gilneas, and do a quest that grants you balance between your human and worgen side, letting you switch between the two forms at will. At this point you've just recently hit level 10 and got to choose your talent spec.
Now to prevent this from being a massive wall of text and to prevent spoilers, let's just say you do eventually finish off all your business on the island and the end quests are quite fun. Supposedly there will be a video to play at the end of the starting chain, but it wasn't yet implemented in the beta. By the time you've finished here you're level 12. Again, here are some relevant screenshots and even more will be uploaded to palolo.us soon. (There are no major spoilers in the screenshots I posted here, but there are plenty on my personal site, so you might not want to check them if you don't want to ruin the story line.)
