Using AZdecrypt v1.19 software on the scroll message . . ? Maybe some folks on here should give that a try?

"Grynix ernum quey ki skebow rednim u os dey wefna enocarn aquantana"

IIRC, there was also an interview of Doug Bell about it, but he had forgotten all about this scroll...According to Bob Retelle who was a consultant for FTL and wrote hint books for both Dungeon Master and Chaos Strikes Back, this scroll is "Another red herring... this was left over from something that was going to be included in the game, but was left out at the last minute... don't worry about it, the scroll can't be decoded..."
