The game

Everything a kingdom needs

A walled city with a keep, fields, a sawmill and a quarry outside the walls

Build your kingdom

Start with a single Keep and grow it into a walled city. Farm food, wood, stone, and ore, collect taxes, and research at the Academy to unlock stronger buildings and troops. In time, found a second city.

A dwarf, an elf archer and a mounted knight fighting side by side

Raise an army and fight

Choose your people: Dwarves, Elves, or Men. Train foot, ranged, mounted, and supply troops, clear six story campaigns, scout your rivals, then march on other players' cities and take their wilds.

Alliances and weekly tournaments

Join an alliance to reinforce each other, share resources, raise your alliance's level and bring down alliance bosses together. A new tournament runs every week, for solo players and for alliances. When an alliance wins, every member gets the full prize.
