1) What happens to characters who are not in the inner region when this ending is revealed?

2) If they aren't killed, should they roll too or will they just keep living their lives like happy adventurers?

3) Surely, rolling the die is each characters full turn, they don't move do they?

•When revealed, all characters in the Inner Region are teleported to the Portal of Power and your turn immediately ends. Characters cannot enter the Inner Region for the rest of the game.

•At the start of each character's turn, he must roll 1 die to see what happens to him. He adds 1 to his die roll for each fate he has.
1-2) He is killed
3-4) He loses 1 life
5-6) He loses all of his fate
7+) He loses 1 fate

•The last character alive wins the game!

1) Characters not in the Inner Region stay where they are when the Ending is revealed.

2) The instruction is followed "at the start of each character's turn", so all characters have to roll when it's their turn.

3) Characters take their turns as normal (move, encounter, etc...), but they also roll on that table at the start of their turn.

I think you're somehow convinced that this Ending works like other "static" Endings, but it is more similar to Spreading Flames from the Firelands. The Inner Region is "sealed", then characters wander around the board until the Ending kills them all, save for the winner.

I made the same interpretation of 1-3 buy yes, I was expecting something a bit more like the static endings.

What got me puzzled was that there's no real advantage of being the first character to reach the Crown of Command. You'll be the last to roll which saves you ~1 round but you have probably invested more life/fate when getting there which puts you back >>1 round.

Also, you can't enter the Inner region but the characters in there are free to head up to the Crown again (for no good reason).

Anyways, like you said, it makes more sense if you compare it to Spreading Flames. Thanks for the answer!

That's the reason why this ending can be played only as Hidden variant. It won't have much sense if revealed.

The first paragraph says all characters in the Inner Region are teleported to the Portal of Power. From then on, no character can enter the Inner Region by any means and nobody will reach the Crown. There's no good reason to do that, like you say, but the Ending also prevents this from ever happening.

That was just bad of me, for some reason I read Plains of Peril ..
