"621, I'm detecting an energy signature nearby- What is-?" Handler Walter's voice cut out, replaced by the loud sound of static that overwhelmed all communications for a few moments, before the radio went silent. The pool of water that you hovered over began to glow red beneath the surface as the dormant Coral began to resonate.
A loud whistling sound came from the sky, before it descended into a loud screech, something quickly dropping down and hovering just over the water ahead of you.
CEL-240 hovered there in the air, it's tipped legs barely tapping the surface of the water, it's large wing-like mechanical parts flared outwards as it watched you closely, the red slit across its head glowing.
It cocked its head slightly, watching you closely, as if it were sizing you up. The silent machine waited for any move to be made, small surges of Coral circling the machine in swarms.
