[Micah]

Your pretender spreads dominion, so if he gets killed you lose approx. 3-4 temples' worth of dominion spread per turn, but nothing aside from that.

The 40 figure is what the book gives, but isn't 100% accurate. I have put more than 40 points into calling and not had my pretender come back til later (it was a 2nd death, so that may affect it, but it's not always 40 from my limited experience)
