The Cavoryte scuttled down the long, dark tunnel. Its heats senses (which I will, for convenience, use to describe heat as colour) noted the perpetual blue-black marbling of the dark tunnels gave way to a pink chamber, filled with blazing orange and fiery red figures.
This creature was a digger. It crawled up to another digger and began to pulse a distinct heat signature. The other creature immediately took notice and began to do the same. Quickly, the signal had spread to the entire area. The first Cavoryte set off out of the chamber and down into a tunnel. The others followed it.
Twisting left and right, the column of arthropods deftly navigated through the labyrinth of the lower nest. They passed by several underground pools and an egg room before reaching the end of the line. The first Cavoryte jabbed its sharp, flattened claws into the packed dirt. Repeatedly picking away in several places, the soil began to loosen and fall away. Scooping away the debris, the digger behind it pushed the dirt further away, forming only the beginnings of a long chain.
The creature continued on for several hours until it collapsed from exhaustion and dragged itself back to the upper chambers, where it could eat and rest before returning.
In the feeding chambers, a forager passed by the famished digger. The larger Cavoryte dropped off a pile of greenish organic matter, possibly from a Zeeboo or Fanel, then set out back for the surface with its gathering party.
The Cavorytes met up with a warrior contingent near the surface, then emerged out of the blue/black world into the varied landscape of the surface. It immediately headed out for the latest food source in its memory- a large, wind-fallen plant a short distance from the nest.
A brief march later, the arthropods reached the site. The forager's cutting claws quickly went for the succulent plant matter in the middle as it scuttled onto the fallen Fanel.
Without warning, chaos broke out. Flashes of light came from all directions, and the Cavoryte dropped into the partly-hollowed stem. It observed a group of two Venatorytes- small ones, with underdeveloped crests. Nonetheless, the small crests were open and blazing with heat as they gave off their colourful and intimidating display.
Perhaps the two immature predators had only been 'playing' (for lack of a better word to describe their behaviour, as they did not have the intelligence to do what you or I would describe as 'play), but things rapidly escalated. Four warrior Cavorytes charged. One crushed a Venatoryte's leg with its heavy claws. The creature let out a horrific screech, which registered to the Cavorytes as only a jarring vibration.
The injured Venatoryte attempted to pull away, but the Cavoryte's grip was firm. A second warrior began to advance. The uninjured partner of the first Venatoryte, torn between its desire to flee danger and its need to stay with its sibling, hovered indecisively behind its brothers, making threatening displays with its crest and claws. One warrior got too close, and was impaled by a lucky jab from the Venatoryte's claw.
The Cavoryte holding onto the juvenile predator's leg released its grip as a hard blow glanced off its side, shaving off some of its exoskeleton. The wounded Venatoryte hobbled away on three legs, making a pitiful whining sound. Its sibling quickly moved back to its side and the two creatures retreated back into the Fanel forest.
The Cavoryte foragers returned to their search for food, as if nothing had happened. They cut off as much as they could, then set out back towards the nest.
The wounded warrior Cavoryte led the way for the group. Its limited senses were on alert. It instinctively knew of Venatoryte behaviour- children were never far away from adults, and adults would fiercely defend their offspring.
Returning on the same path which it had departed on some time earlier, the nest was reached in a matter of minutes. The warrior stopped at the entrance, watching its charges move into the near-total safety of the nest.
The Venatorytes struck without warning. No fewer than four mature specimens burst into the small clearing around the nest. Two foragers were killed on the first strikes.
The wounded warrior instinctively charged towards the aggressors, giving off the signal flash at the same time. It made several attacks at the feet and claws of the predators, though they withdrew too quickly to hit. More Cavorytes were dying every moment, though the warriors were beginning to fight back. The injured warrior noted that almost all of the foragers were safely in the nest. In addition, it realized that all of its combat-capable bretheren had been incapacitated or killed. It began to retreat towards the nest- and safety. The last of the foragers entered the den, and the warrior dropped into it. One last blow bounced off its curved exoskeleton before it retreated out of reach.
The star Panzerus was just beginning to rise on the horizon, or it would were the horizon not obscured by a thick forest. A few beams of light and warmth penetrated the plants and morning mist. A few warbling Venatoryte calls sounded through the dawn air as they dragged off their kills to be eaten. And below ground, the Cavorytes feasted on the days harvest, and began to prepare for the next night of foraging.
Note on Size: I picture the Venatorytes being around the size of a small to medium sized dog (around 50 cm long when mature), while the Cavorytes are never larger than fist sized.
