RampantCoyote's blog has been sporadically updated with bits about his upcoming indie RPG Frayed Knights following the test version/demo release. Here is some discussion and a bit of status update a while ago, and more recently he gives us a lore update.
Originally, this tower was called the "Tower of Certain Death" by those few locals and adventurers who knew of its existence. Every once in a while some local youths from nearby towns who fancied themselves as adventurerers would discover legends of the tower, and mount an expedition to find and sack it.
Of the few expeditions that found the tower, most ended in the entry chamber, not with death, but with a lot of ale-drinking and graffitti-drawing to mark the accomplishment. Then the expedition would return home with tales of surviving the Tower of Certain Death.
At this point, jokes circulated renaming the old tower the "Tower of ALMOST Certain Death," as it was clear that merely entering the tower did not lead to instant demise. Those who remembered the old stories warned that it was actually ascending to the top of the tower that resulted in certain death, but as the young trespassers who had survived entry chamber parties maintained, the tower was in such poor condition that a lethal fall from the top when the floor gave out was a certainty.
