1) If I conquer an area in an enemy home realm, can I build a stronghold there? I don't see anything preventing this in the rules but wanted to double-check due to the next question.
2) If I build a stronghold in another player's home realm, and then I move my units away, who controls the area? On the one hand, I control it because I have a stronghold there. On the other hand, they control it because it's in their home realm and contains no enemy units.
