If you want to get onto the Stage, that's great!
Right now, the Stage is still being tested. In the future, I'll make available a quickstart guide that'll help new people get into the game.
Can't wait until then and want to get started now? Then join the playtesting! The core material is available for you here! The core material is free; in the future, I may offer additional material at a charge. If you're interested in testing some of that material, let me know!
If you want a little more insight into the campaign settings I'll be publishing, you could read some of the lore and tales! Or, if you want to see how a campaign progresses, check out the campaign logs!
