I've been hard at work on a Web client for Empyreal
and it is coming along real well. Yesterday we had a small play through with a couple of Alpha testers. The Manual is already available (being updated regularly) and you can find it at http://enchiridion.dalin.es
If you want to be able to participate in the upcoming Alpha and Beta phases make sure you head over to Dalines: the Lithium Project sign up for an account and get to Level 3 - Master as soon as possible.
