Directive: Sense evil. Locate, then eradicate. Click. Whirr. Tick-tick.
I know why I have been designed. Must fulfill directive. Tick-tick.
YEESHA was a beautiful and monstrous thing. Built of copper plating many feet thick, fortified and coated with twenty-four-karat gold, the clockwork arachnid was a glorious sight to behold. She stood as tall as a high hill, if not a mountain, and the span of her eight legs sprawled exactly one thousand feet, combined. She had eight eyes around her head--lenses of massive proto-cameras--and almost-invisible wire-hair sensors all over her body. YEESHA had a head, thorax, and abdomen, as natural spiders did, and she was technically female. However, since she was mechanical and not organic, she could not lay eggs. This was her one flaw. In all other respects, she was perfect. Impregnable. That was the way that the Council of Mechamagicians had built her to be, and she would serve the purpose for which she was built.
As for her nervous system and "brain", they utilized aspects of technology and magick, with organic and synthetic parts. The core of her being was a glowing icosahedron of sentient essence, which was being carefully monitored--and, unbeknownst to the primitive YEESHA, enslaved--by the mechanical device, a metallic tape-loop, that housed and read off the parameters for being 'eradicated', feeding them into her barely-sentient proto-consciousness. She was an intelligent being, but not yet a reasoning one. Little by little, it caused YEESHA actual pain in her organic nerves to listen to these parameters over and over. However, this pain was so subtle, so slight, that it was absorbed by the metal plating. This would not always prove true.
Once more, the Young Evil Eradicator, Suppressor, and Hemisentient Arachnid sensed the parameters that she was being fed.
The parameters continued on and on, almost without YEESHA'S conscious knowledge, until:
Non-procreative carnal acts...evil.
Non-marital carnal acts...evil.
Hurting others' feelings...evil.
And, finally, the one parameter that had even broken Yery Wisdomgiver's will:
At the end of these parameters, there came the hoped-for results.:
THERE WILL BE NO MORE SUFFERING.
Click. Whirr. Tick-tick-tick. Directive. Must discern if parameters met.
THERE WILL BE NO MORE WRONGDOING.
THERE WILL BE NO MORE CHAOS.
Unbeknownst to her massive frame and tiny spider brain, YEESHA felt...pain.
