In my campaign setting there is a science and magic based nation, called Hyperion, who have designed a race of magical constructs. These “Shinies” were developed as a means to replace menial laborers and soldiers. What the Hyperian scholars didn’t know was that the magic infused in some of these constructs had slowly started evolving into a much more complex design. Unknowingly creating a race of sentient machines.
I really enjoyed designing the Shinies, creating them as a reflection of our own technological advancements. Chock full of references both in the names and the backstory. The fact that they are manufactured in the East. Their nickname as another reference to the Chinese, the Shinies. Naming the first one M-Sheen, or basically Machine. Piecing it all together, making sure it all still makes sense.
