I was thinking of adding a game turn limit card called "The Rat King" (had to think of something evil and nasty to take control of the land).
The basic idea is this when it becomes night or day (not day to day, or night to night) one fate counter is placed on "The Rat King" card (much like the lightbearers ending card). If at anytime there is no more fate counters left in the fate counter pool for "The Rat King" to take the game ends and it wins…
You "of course" need the new set but what do you think? Any improvements?
I was going to say "Once a player lands on the Crown of Command all Fate counters are returned from "The Rat KIng" and his card is removed from play" as well on his card.
Of course the Lightbearers ending can not be used with "The Rat King".
