20 WP each season?! But we only make 5!

Sorry for the confusion. 
One season = One Turn. 
Four seasons = One Year

Debt & Income is [b]per season[/b]. So Veranth nets 20 wp per year and has a current debt of 4wp per season or 16wp in debt per year.  

EDIT: Guys, bare with me, the game isn't quite open yet and I'm working out the details.
