The game is set in a ancient fantasy world of kings, wizards and fearsome creatures.
It is the player's task to organise the opposition to the invading forces, uniting the kingdoms into an alliance and ultimately in taking the war back to the invaders. As the various characters encountered across Ashworld are recruited to the player's cause, the player can then move them around the lands, having them performing a variety of activities, such as hiring mercenaries, buying goods and provisions, and attacking hostile forces. Legions of Ashworld is a turn-based war-game, which brings a sense of adventure to strategic war-gaming with its first-person view of an open world environment.
