I busted out the Rolemaster Creatures & Treasures book this morning because I was reminded of one of their oddball treasures.
I figured I'd look it up and see if I could use it or a variant in my own games. But I stumbled on this:
"Rune of Illiteracy: All within 50' cannot read or write for 1-100 days. (Also known as the Rune of Fluvanna.)"
Pre-internet, that was meaningless to me. No longer. Fluvanna is a county in Virginia . . . and the writers and producers of the book were based in Virginia.
(My old home town gets slammed repeatedly in Futurama, so I'm still one up on the Rolemaster guys.)
