So basically your faction has to control all 5 keeps around the central capital of Cyrodiil in order for an emperor to be crowned, which is going to be the player with the highest stats.

1. What does the highest contribution mean ? Most damage done ? Most healing done ? Average of the two ?

2. What if the emperor logs out ? Do the bonuses he provided to his faction end because he's offline ? What if he moves to another campaign ? Does he lose all his buffs in that campaign cause he's not THE emperor there ? Does his current faction lose their bonuses cause their emperor is gone ?

3. Once an emperor has been crowned, when can another be crowned ? Is there a cooldown ? What if the emperor's faction loses one of those central keeps and then gets it back in like 10 minutes, will an emperor be crowned again now that all 5 keeps are owned once more ?

I'd like to know more confirmed details too, I think most of us would.

I don't really remember, but:

1. All

2. If he logs out when a keep is down, there is no emperor, iirc. If he/she logs out and your faction continues to have all the keeps, you keep it. Your faction continues to get the bonus as long as your faction has the emperor, if he is there or not.

3. Death, the next faction needs all the elder scrolls. If your emperor is still alive, he's still emperor.
