What to read after Arthur's Legacy ALPHA?

Arthur’s Legacy (Alpha Release) is the alpha/incomplete release of an Arthurian modern fantasy setting published with a unique diceless bidding system. It is suitable for the production of storygames, collaborative storytelling, and roleplaying games. It depicts the return of the Isle of Avalon, an event called the Rise of Avalon. The Rise triggers a Rebirth and a new mystical Age is called into being. King Arthur, Prince Mordred, and other legendary figures rise from Slumber and otherwise return to the world. 

The actors in a standard production portray knights with mystical abilities who are evolving into avatars of the ideals they call upon. Knights are ordinary people who suffered nightmares and flashbacks before realizing that they are reincarnations of knights who served in previous semi-mythic Ages. Just as the immortals who rule over them and their predecessors were great men of myths and legends, the knights of the modern Age of Lightning are engaged in weaving a new body of grand stories and epic tales. Arthur’s Legacy is their tale of struggling to adapt as they evolve and try to puzzle out the nature of this Age.
