The undead invaders in Fire Emblem Awakening are called the Risen.
The Risen are revenant monsters that threaten the continent of Ylisse during the game’s central conflict. They are connected to the dark magic and resurrection experiments pursued by forces in the hostile nation of Plegia. Their appearance turns an ordinary political war into a supernatural crisis.
Fire Emblem Awakening’s story follows Chrom, prince of Ylisse, and the Shepherds, alongside the customizable tactician Robin. The army battles the Risen across the campaign, while also confronting Plegian forces and the larger threat posed by the Fell Dragon Grima. The Risen therefore function as both recurring enemies and evidence of the enemy’s forbidden power.
They are easy to confuse with terms from other Fire Emblem games. “Laguz” refers to shapeshifting peoples in the Tellius games, while “Emblems” are legendary heroes represented by rings in Fire Emblem Engage. Mila’s Turnwheel is an Echoes: Shadows of Valentia gameplay device, not an undead faction in Awakening.
