Ljäquotels
Ljäquotels are a hypothetical species originating from the planet Xylos, a tidally locked world orbiting a dim red dwarf star. Their biology is adapted to the extreme temperature gradients present on Xylos, with distinct physiological differences between individuals residing in the permanent twilight zone and those on the frigid dark side. Ljäquotels are characterized by a silicon-based exoskeleton and a complex internal circulatory system that utilizes a copper-based hemocyanin analog. Their primary sensory organs are bioluminescent clusters that can detect subtle changes in light and heat signatures.
The Ljäquotel civilization is known for its intricate subterranean architecture, carved into the planet's crust to
