Guard of Fomortiis

The Guard of Fomortiis, as the name implies, are the personal guards to the Demon King Fomortiis who're led by an unknown entity. The Guard is dreaded by the Nations of Detrox, including the Arcadian Federation, due to the large amounts of damage they've caused over four million years ago when the Realm of Light was at war with them. Little is truly known about the more complex information about the Guard, such as possible ranking systems, tactics, etc. But a single fact stands true for everyone:  Do NOT attempt to fight one of them, as even the strongest of soldiers can and will fall to them even with backup. 

WARNING: SPOILERS BELOW!
