Just speculating here, but it seems to me to have a high level basic D&D feel to it, possibly like something from the Master Set or perhaps the Immortal Set modules or maybe even from the DA-Blackmoor series. I pulled all my Basic D&D stuff out tonight to check to see if I could find it, but everything I checked either didn't have it or it was shrinked.
Hopefully someone else can maybe check their stuff also, to see if my suspicions are correct.
