Altering / Improving my Kings + Heirs

[Biggus Diccus]

In my current campaign Iceland has had 95% zeal for about a decade now and I've noticed that every single unit recruited there has 9 piety. Coincidence? I don't think so. Can someone tell me if the two are connected? I never had any idea of it, but that seems to be the case. Sorry if this has been discussed years ago.

This is indeed true Galagros! In my current Polish, early, GA, hard campaign I checked to see if this happened with me as well. I currently only have two major troop-building provinces: Poland with 60+ zeal and Moldavia with 10+ zeal. The units trained in Moldavia all have piety around 0-2, while those trained in Poland have piety from 4-7. Never noticed this before
