The story

Six banners cross six borders in the same week.

Old King Edric is dead, and his 17-year-old daughter Alys has worn the crown for one month. Then six banners cross six borders in the same week, and nine more powers follow them.

The court calls it bad luck. Cadoc Stormwright, the court wizard, calls it a plan. You hold the CrownWall: every front, every gate, every map.

Why did fifteen enemies strike at once? And who stamped their silver with a winter star?

Every border. Every banner. One crown.
The Kingdom of Avelmark

The fronts

Fifteen nations, five battles each.

Every nation fights its own way, on its own ground, and every front ends with its general in the field. The Winter Empress waits at the end.
