Hi,
Has anyone ever seen or heard of "The Finding of Morillion - The Fifth Excurstion of the Vikings" by Don H Green and Gary Preston (no publisher)?
Adam Thornton shared an image of it and how he came by it here:
athornton | TroveIt was a ziplock bagged adventure sold for $2.
We've both looked through it to try and date it. It references Monster Manual, and psionics from Player's Handbook, but appears to assume you're still using the original booklets, so it probably dates from 1978/1979.
