basic question on heroes

[knightpraetor]

When you switch religions, do you lose old religious heroes? i would assume so.

 

[retro V]

Religious heroes leave your service when you switch religions, but they can be rebuilt. Say you left RoK, Bambur will leave you, but another civ with RoK can then rebuild him, so can you if you ever go back to RoK and he is still available.
