#TTRPG – Does anyone know anything about this game? IMPERIL?

Does anyone recognise this cover, or anything like it?

Apparently it’s an old game, perhaps an early RPG or RPG-like boardgame from 1980 that only had a very limited release.

I found the image in some of my old zip archives, but can’t remember where I got it. There doesn’t seem to be any other material in that archive (just some very old ‘zine content from the mid 70s) and any help, or even speculation, would be appreciated in tracking down more information in Imperil or ‘WISS’.

Cheers,
