Villainous to their core, the Black Knights are the source of many a dark tale within Lyonesse. They are a contrast to the blessed glow of chivalry and heroism seen so often from honorable knightly orders. There is not light without shadow.
Some believe a dark force unites the Black Knights, and drives them onwards to common purpose. However, they are rarely seen in groups of more than a handful. Others claim that the Black Knights are simply a catch-all for all of the villainous knights within the realm of Lyonesse, both Above and Below.
