Well, that makes me rather less excited for that one, but if you end up running any of them, I'd be happy to play and help anyone else who needs to learn spheres. Ian, do you have a preference of the paths he has available?

Ian's obviously got first (and really only) call here, but I had a question about Way of the Wicked - is it full on nasty evil, or is it more anti-heroes/byronic heroes/mistaken for truly evil/etc in nature?

Spheres of Power basically sets casters on a linear progression (rather than quadratic), and lets you customize a caster's magic to a greater degree with 'spells' (Sphere abilities) that scale for your whole career and give a large variety of viable options (so you can't guess with 80-90% accuracy what 'spells' a caster will have at any given level). Spheres of Might allows more customization for martial classes, giving lots of different ways to focus and fight.  It does it without making it into a mundane spellcaster or having the painful tracking issues of Path of War (Pathfinder's Tome of Battle). Everything is available at: spheresofpower.wikidot.com.

I'd be down for pretty much any adventure path done with Spheres in a hot minute.
