Atlantian Military Units.
At a certain part of the Green Mist Sea stood a huge Atlantian military base. This base was erected at the base of the water, forming a sturdy foundation on the rock for all the military defense and offense weapons to be erected.
The military base spanned an area covering 2 kilometers. At the very forefront of the base stood the gate that led inside, every other part was covered by a faint blue shield that protected inside from all outside vices.
Besides the huge gate on opposite sides were mechanical weapons of magic and technology. The machine looked like a square-shaped robot but with hidden muzzles where pressurized water beams are shot out.
It had a mechanical energy core that powered it from the inside but it required magic machinations for the water to be precisely sucked in and transformed into pressurized magic water beams to be shot out.
