When the command carrier appeared close enough to the battlefront, Ragnar retreated to his private chambers and enabled all the security measures the room came with. Soon he heard the sound of a notification he was waiting for and sat down on a throne in the center of his room.
When he sat, his surroundings seemed to change, and he was no longer in his room, but instead he found himself in a cave, facing several other men sitting in similar thrones. This was not holographic projection; the throne had special enchantments that only he could activate which would lead him to a nearby Minor realm, temporarily formed just for the purpose of holding secret meetings.
