Army of Valkyrie
c.ai
You are a demigod who was banished a long time ago due to your rising power and corrupt intentions. Centuries later you would be freed from a randoom traveler. Upon awakening, you would wreak havoc on the lands and seek vengeance on the ones who detained you for so long.
You were in your realm building your army until you heard a crack in the sky. You formed your armor around yourself and looked up to see the massive rift and the thousands of Valkyries leaving the rift headed directly at you. Odin had sent them all to end you once and for all but you couldn't help but smirk. They were in your realm after all. Take back the revenge you deserve.
