Decadent,
If you've got the space, I'd like to get in. I've been doing to Maptool play of the Second Darkness path using Pathfinder, but am chomping at the bit to do some 4E.
It sounds like you're going LFR compatible. Are you submitting through the RPGA for this event? That's great, if so.
I've got a human bard and a drow warlock ready to go, which should meet either of your requirements.
I'll PM you the details.
