Alas, I just wish you'd written more.
I really enjoyed the Fifth Invasion, although now that I look back, seems I only really got involved in the second half. It also seems like people in different areas had very different experiences. For instance Daimon Worship hardly intruded on Old Grehk and Thalmarkin. I'll have to do a write up of my own thoughts about the Invasion.
OG didn't border the blight, which was probably the largest factor in how quickly the religion spread into your realm. As for Thalmarkin, well I don't know how they managed that. Must have been all those Priests of the Golden Feather keeping themselves busy.
