In a distant realm, the Embliam Empire and the Kingdom of Askr are locked in battle over dominion of all other worlds. You–the player–are a summoner with the ability to call upon heroes from the multitude of Fire Emblem worlds and timelines. Fighting alongside the Order of Heroes, which includes Prince Alfonse and Princess Sharena of Askr, your task is to protect Askr from this never-ending war. The game is free to play, but you can purchase gameplay incentives using real currency.
