I am very excited, already things are starting to come together nicely.
I want to thank you for volunteering to lead your Houses, without you guys this game would be much, much smaller (if it existed at all).
Your first order of business is to organize your Houses. Discuss with your House how to coordinate backgrounds and such to make your House's more cohesive.
Secondly, you are to police your own. Check out builds and try to get your minions on an even keel. Beware of ACs over 40, and saves above 30. Also, be alert for characters that seem to have too many immunities (a couple is fine, even expected). You want each member of your house to have some sort of vulnerability, as invulnerable PCs will be shot (and not replaced... at least not right away) when I get around to inspecting sheets. Damage out put can be very high, I'm ok with that... as long as there is some chance of them missing their targets. At this power level your minions will be facing creatures of their CR +6 or greater. Weaker creatures should be slaughtered fairly easily.
Thirdly, I would like to start a collective pool of encounters that we may all use. If somebody stats out an advanced / templated Displacer Beast (or whatever), please post it. The more resources we have that can be recycled the better.
