The Battle Command was an institute formed under the will of the demon-hunting expedition's Stigmata Sorcerer to lead and draw up all the Demon-hunting Sorcerers' battle plans. It wasn't someplace that a normal Demon-hunting Sorcerer could waltz into.
Sometimes, the Battle Command would directly contact Demon-hunting Sorcerers who have earned Honor Badges, but they would not meet physically.
They were like the spiritual think-tanks of the demon-hunting expedition. They would receive the highest order of protection from the demon-hunting expedition, mostly from the Dawn Sages as well as a few demon-hunting trial members.
The normal Demon-hunting Sorcerer that gave out missions were merely shadows of the Battle Command. They were called the messengers of the demon-hunting pact. They were just ordinary Bright Demon-hunting Sorcerers.
The room within the metal aircraft wasn't very spacious.
