1 Pretender and 1 Prophet?

[customer717]

I just finished my first successful (ie I was winning) "walthrough" demo game. I am waiting for my full Version now. I have many lingering questions, but some stand out.

1) I had a Pretender and a Prophet. When I killed the enemy Pretender he was still in the game vowing to kill me to the Last man. So I guess they are just a "bonus" for domain spread, but can still die without the game being over. I assume the are dead forever and you can not get a new pretender?

2) Similar deal, my Prophet died and I could not get a priest to become a new one. I am almost certain the AI was making new prophets when one died. How do I get mine back?

3) I had lots of water summons, but could not use them. Do I have to be IN WATER to use these? If so, how do I get my mage to go in water as most of my troops won't go there (undead were the only ones that would)?
