Adventurer
Alrighty, I'll review the story materials you've given and such and try to get a concept up in the next few days(I hope there isn't a rush).
My initial ideas at the moment aren't very solid (I'm still new to 4E and looking to try different things[with the PHB and PHB2, those are my two sourcebooks]) but I'm thinking of trying a leader or controller type, if anyone has any particular preferences on the mechanical side. I'm sure I'll be able to tie it into the IC.
Edit: I'm reviewing the wiki now, but am having trouble locating the relevant sections. Which area is it that would give information on the immediate setting of this adventure? If I missed it, apologies in advance.
The Witchlight Strand This is the general area you'll be adventuring in. The Witchlight phenomenon is currently in full effect at this point. Take that how you will...
Port Magalie This is the city you're starting out in. In particular, the current group is partaking in the celebration at The Wyvern's Nest, as indicated on the map.
The image of the Wyvern's Nest building was done by 12rounds, another extremely talented CG member. The maps of the Witchlight Strand and Port Magalie were created by yours truly. You can tell I've still got some learning to do.

While you're at it, check out the regions of Thrubmorten Fens and the Tawaren Basin, by Redrobes and Midgardsormr respectively. Some wicked talent there.
