Core setting: Ordinary Delta Operations players accidentally physically travel into the real battlefield world of Ashara. There are GTI operators, the Hafk Group, and the Asara Armed Forces here. Dam Zero, the Tower of Babel, the cement factory, and the space base all really exist. Guns, armor, Hafcoins, and the evacuation mechanism are still in effect. However, under this land, there are buried auras and ancient spiritual traditions that have long been forgotten by modern warfare.
