While arguments can be made for all factions, I believe Lizardmen should not get Diplomats. Not only for the fact do I believe they speak a totally different language, the Lizardmen aren't necessarily enemies to everyone, but they can be safely put into the category of being friendly with no one. The only race even closely related, the elves (WHo were raised by the Lizardmen) recently lost favor because of Dark Elf raids to the temple cities (The Lizardmen don't discriminate from the 3 elf 'species'?

As to spies an assassins, you can make them as followed:

Building: Chameleon Spawning Pool: The chameleon skinks have long been famed for their ability to get close to their prey without the slightest notice. There blowpipes are silent killing weapons for their unfortunate target.

Chameleon Hunter: Assassin
Chameleon Gatherer: Spy

The priests can be classified as Skink Prophets, if religion is factored into the Lizardmen Race. If possible, having these different levels of temples can also factor into characters gaining traits/anciliaries of the old ones I put into the Traits/anciliaries thread.
