Weapons of Old Vol. II: Knights in Shining Armor

From publisher blurb:

The second volume in the Weapons of Old series focuses heavily on magical items from Arthurian myth and the Middle Ages. Holy artifacts from Christian myth, including the Virgin Mary’s sacred mantle, and several versions of the mysterious Holy Grail itself. Many of these items were created with La Morte D’ Arthur and its comic-book sequel, Camelot 3000 in mind, and are designed to be included in a generation-spanning campaign featuring the Reincarnated Knights of the Round Table.
