I have a collection of notes on magic items and history for a campaign I ran a few decades ago. Over the next couple of weeks I will be posting them here. The first item is the Band of Roland and was likely written during a Black Flag phase I was going through. It has been updated for D&D 3.5.
As I mentioned, these items were used in a campaign and actually created by an persons in the game. This explains the comprehensive background on such a small magic items.
