Things are really taking off. Tons of plot and conflict right now, so get in while the getting is good. As long as you are not an ooze lover, you are eligible. Few religious factions have the freedom of concept and behavior that the chaotic Mystryl does.
Feel free to PM on the forums or irc (Skovox), or check out #crucible.
The Crucible has been an enjoyable source of conflict and I recommend players new and old to give it a try if you are unsure what to do.
