Ethnos
How is a Kingdom scored in a 2-player game at the end of the Second Age?
The two-player special scoring section states this directly.
- Ethnos rulebook · Rulebook · Special Scoring for 2-Player Games
The player with more markers takes the Kingdom's highest token, and the other player takes nothing there. If only one player has markers, they take both tokens. At the end of the First Age the winner takes the lowest token, as usual.
