Well, the Redcap would be modded to be tiny rather than small, as would anything else that is not tiny, but it was originally conceived as a break from the regular game still within the same storyline. Them playing the gremlins and such would be a witness's testimony as to the event the regular party would have to deal with.
Plotwise, I thought of the gremlins wanting to wake something up, then wreak havoc on a town in the process. then whatever they wake up would have to be an enemy for APL 5+.
Thoughts, suggestions, scrap it?
