The Shield of Blood Knights has been rumored to exist as a symbol of honor and valor during the era of the Crusades according to local archaeologists and historians. Only persons of honor or nobility and accomplished knights could brandish the shield. The symbolic image of the shield according to historians is depicted as two swords crossing behind the shield, with a seven-pronged crown in the center, serving as its crest. The crown is gold, and the color surrounding it is blood red. Shields were commonly used by knights in battle to serve as a means of protection, in addition to armor or chain mails. The most common material used in designing shields was various types of wood, including poplar, lime, or other resistant types of wood. According to local historians, shields belonging to those of high stature often had crests carved or engraved onto them. In addition to crests being added to shields, some were lined with metal, the most common metal being iron. Iron ore is a malleable alloy, and according to local geologists, was easily accessible during the era of the crusades. Aside from shields, various weapons and armor were crafted from iron ore, as well as eating utensils and tools. Once a knight was proven and established as a glorified war hero, he ascended to the title of paladin. According to local historians and record keepers, paladins were considered the most honorable knights during the crusades. Paladins were identified by the shields they carried, and the armor that they wore.
