Metal sphere

Mysterious constructs that seem to appear intermittently near the Barrier. The spheres fly, but do not seem to use magic to do so. Makes a high-pitched noise when moving at high speeds. They are about 1 yard wide.

Behavior
The spheres attack seemingly random targets with beams of fire energy. When hit, sometimes targets will disappear entirely, leaving behind only scorch marks, the target's clothing and/or belongings, and traces of ash.

The second sphere encountered by the adventurers appeared to self-destruct, a feature that did not seem present in the first construct.

Construction
Milla Kramer disassembled a sphere after its successful defeat by Kika and Fan Brightgrass. Within, she discovered three small orbs containing three abilities when activated with lightning energy: Milla also discovered several plates with bizarre metal engravings, and cables made of an unfamiliar material.
 * 1) Shield: green orb. Creates a green, shimmering shield around 2 yards in diameter around the orb. Appears to have no practical effect.
 * 2) Fire ray: red orb. Fires the sphere's beam attack in a straight line.
 * 3) Lightning: blue orb. Hums and glows with lightning energy when reactivated.

Milla used the fire ray and lightning orbs from the first sphere defeated by Kika and Fan Brightgrass to craft Destiny, her ray gun.
