I wish it were a joke.
Seriously though, if any of you are aware of Keep on the Shadowfell, the first leg entails fighting against a lot of kobolds, then against a lot of goblins, hobgoblins, skeletons and the like. It's standard 1st-level stuff. However, for this, since you guys are beginning at such an advanced level, comparatively, the first encounter will be against kobolds with class levels and one or two "lieutenant" type creatures. However, there is going to be a vast departure from the adventure as written after that as the plot thickens. You guys should gain a couple of levels before the end of this leg of the campaign, at least that's the intention.
I hope that's ok with you guys.
