[@Leotamer] Shit, I must've forgotten to cover that in the OP.

A plane costs 1 Might and can be sensed by other gods, but may take some effort to enter uninvited. Creating things inside the plane costs the same as creating them outside of it. Jury is still somewhat out on whether or not Sanctuaries can be built inside private planes (probably not). Planes don't have an awful lot of space- you could fit a city-state or a small island in one, but not much more. Gods are restricted to one plane each.

When you create a plane, you get to choose what it's like, terrain-wise- it might be all water, have no gravity, be made of solid light, be 100% stone-carved tunnels, or whatnot. To change this, you'd probably have to either spend Might or re-create the plane. Only the creating god can do this, and the creating god has power over who can enter or leave.

That should be it!

Welcome! Don't worry too much about catching up. If you read, say, the last page worth of posts and go through all the character sheets, you'll be just fine.
