Breaking some of the worldbuilding into chunks for delegation. Presuming you are all willing when you are done I'll dive in after and reattack/flesh out before posting finished versions to pinned game threads.
This is accurate on all counts other than I want to dive deeper re: Athlone. A dark court might be just what we need as well.
Would you perhaps take on doing a writeup of a couple of paragraphs each of fluff for Faerie Courts? Just general character/flavor and any significant NPCs and/or centers of gravity that come to mind.
Would you be willing to work on sections under the immediate surroundings of the lake? I have in mind a small but growing village immediately on the shore that has newfound activity and ties to the Covenant now that Inchmore has been built. The rest are just the nearby mundane lands/villages and lords etc. Other than the Monastery with which we share the lake, on another island north of us.
@Nithyn has the library and vis sources to work on.
I will start taking a deeper stab at Athlone and whatnot soon.
