The draft of the manuscript is online as a wiki which can be found here.
Today I set up a character page for one of my playtesters, who is making a riff on Sir Marrok, the werewolf knight. It turns out back in 1902 someone wrote a whole novel on Marrok, which is giving her plenty to work with. I've also added a few paragraphs to the character creation page emphasizing the freedom players have to manipulate these famous characters to new ends. Many players immediately recoil from playing famous people like Arthur, Guinevere, or Lancelot because of all the personal and romantic baggage which those characters bring with them, but in AL! you really have considerable freedom to jettison such baggage if you don't want to deal with it anymore.
