List of Grimoire Cards/Swarm Princes

""The royalty of nightmare."

The Swarm Princes are terrible legends. It was their will that forged the Sword of Crota, a weapon meant to ravage worlds - the Great Render of Light, the Darkest Edge. They have waited in the shadows of the Hellmouth for their master's return, guarding the Sword and sating its ravenous hunger with the Light of Guardians who have dared to challenge them."
