Change of plans. GK and anybody else who shows up, please start by creating a level 1 character. I've got my hands on Hoard of the Dragon Queen right now, and I really want to run at least part of it, either as a prequel or a side story. (Really, it was false advertising on Wotco's part to claim that RoT can be run without HotDQ; the former doesn't even give you a map of Forgotten Realms geography, and only the fact that I have the 3E FR Campaign Setting made it even vaguely possible for me to play the thing without transplanting it to a homebrew setting.) The five existing characters will continue to play at level 6, either in the future or in a parallel universe; this actually aligns them better with the later part of HotDQ than it does with the beginning of RoT, and meanwhile the newer characters will level up fast and be caught up before long, at which point the groups can begin trading members and spread out across the more expansive RoT scenario.
