Alright, this got rather interesting while I was away.
Lots of stuff to go through:
To AJ: My complaint about a cleric is what AC pointed out. Regardless of which spells you pick *today*, if the boss turns out to be too hard for you, you come back tomorrow with enervation, tweaked SoD/Ss, and obliterate him. Doubly so if this is Dweomerkeeper. AC, is, at best a low-touch AC charger. If I ever want to kill him, I have a low level necro lob Spectral Hand and Shivering Touch, and his PC is a drooling no-Dex heap on the ground. He's great if he gets to go first, but what's he going to do against an NPC with levitate, or a basic SoD spell? He's just not as good, especially once you get higher in levels.
Also, as to Ejo's template, I told him he got no flight, no vision, and just the stats and the 5' fear aura. Lolth-touched is also a no-go, mostly since Lolth just doesn't exist in Arhosa. Still haven't decided on the deities, however.
Another thing is that you parties are, as requested, at roughly opposite ends of the map. AC/Venn/Ejo are outside the Arhosian Wall at the north, while Arthurians have a free hand to build a kingdom down south, without interference from other PCs for quite some time, as I think the Cult is based out of Marleath. Most groups will likely not contact one another till level 7-9ish (I presume), and each will have done a fair bit of world and nation building by then.
And as a final point, no one is perfect as a DM. However, it does work better to remain calm when discussing points, rather than becoming emotional. Makes your points come across in a clearer fashion, and one more likely to be taken seriously.
