Kef-Endu Species in The Kaleidoscope System | World Anvil


Table of Contents
"Blaze flies" were insects employed for carrying explosives into enemy territory.

Basic Information


These insects had streamlined bodies, six legs and two wings of translucent skin. Their hindmost pair of legs was notably larger than the other two and ended in strong grippers. They had large compound eyes which took up most of their heads, and a short proboscis that was folded against the underside of the head when not in use.

Biological Traits

It appears that there were two major breeds, distinguishable by their coloration. The wings of the so-called Nizu-Lemu, literally "night wings", had dark blue undersides whereas those of the Andufi-Lemu or "noon wings" were of a pale violet. The names of the breeds imply that their appearance served as camouflage against the sky at different times, and records from that time seem to confirm this idea.

Genetics and Reproduction

Female blaze flies laid packets of about 10-12 eggs per mating.

Additional Information


This species was bred specifically for its purpose, so it is likely that all blaze flies were born in captivity and trained from the moment they hatched.

Uses, Products & Exploitation

Blaze flies were able to carry weights of about 0.3 kg over mid-range distances. During the second half of the Final War, the military of the Ran-E-Zu Confederation employed them for dropping medium-sized cells of harnessed crystal fire onto enemy bases. While not as effective as a large bomber aircraft, the flies were harder to detect on approach and able to out-maneuver most defense mechanisms.

Average Intelligence

According to military records from the Final War, they were able to locate military outposts and distinguish enemy sites from allied ones. There is also evidence that the flies were sent towards their targets without guidance by people or technology. Historians conclude from this that they were trained to understand basic commands.

Perception and Sensory Capabilities

Blaze flies were famous for their exceptional maneuverability, which was made possible by several sensory organs that are still found in modern-day species. Their compound eyes were able to see obstacles, predators and artillery fire with high temporal and spatial resolution. They possessed multiple orientation-sensing organs along their thorax and abdomen, and bristles on the front rim of their wings let them sense air pressure and the direction of the wind with great accuracy.   Apart from that, their sense of smell was highly developed, and Rilsu scientists assume that they could use it to detect certain chemical compounds found in Rilanga warfare agents.

That's a really cool idea and something I could definitely see militaries start doing when even drones aren't enough. The Final War sounds like it was a real rough time, as befits the name   Really gret stuff :D

Thank you! ^^ Yeah, the Final War nearly wiped out Ranul's population, that's why the Rilsu are so determined not to start any others after it.

Those poor Kef-Endu! Bred for war. This is a wonderful idea though, in my mind unique as well. Something that I can imagine could happen for real if the right insects and technology were available.

Thank you, I'm glad you like the idea! ^^ But yeah, many Kef-Endu died while doing what they were trained for, or when the Rilanga retaliated by destroying their home bases. They did not deserve that, but people rarely cared. :(

Poor extinct bugs. :( <3   The idea of flies bred for things like dropping fire on people is rather terrifying though!

Yeah, the Final War was a time of dirty tactics, especially near the end. I'm glad that you like the article!

Ah, an excellent combo of fun world building and a vivid description of what they look like.   Are a lot of insects trainable in your world, or are Blaze Flies unusually intelligent? I’m intrigued to know exactly how they’re trained, too.

Thank you, I'm glad you like it! ^^ Many insects on Ranul fill the role that birds and mammals would have on our world. So I suppose there are a number of species which are as smart as crows, dogs or horses, respectively. I haven't yet thought about how they are trained, but food probably plays a major role in that. Maybe together with exploiting some natural behavior. I might write an extra article about that, like a tradition or organization related to insect training.
