Second version of Entropy's reference, drawn by  Shapyra! You will notice that the wings are now fully membranous to show off the node pattern, and that there are plating bits on the paws and on the muzzle, as well as a horn of sorts! Oh, and an "official" anthro version too! This version also inplements bioluminescence!

A bit of explanation of the concept, if it helps appreciate the concept better. Two reasons, and two design decisions.

The thermodynamics explanation of "given enough time, any system tends towards disorder" is a concept that has always appealed to me. This is represented by the pendant: an artefact from Final Fantasy XIII-2 - in other words, a time crystal. One of the rare objects that, in theoretical physics, will not see its entropy increase over time, sort of "resisting" it.

But most importantly, I'm a huge nerd, studying computer science and AI. In machine learning specifically, a concept that comes about and is used a lot is Shannon or information entropy. Cross-entropy is a critical part of neural network learning, which leads us to design pattern number two: the wings. Idea was to somehow represent this concept of entropy on the body, and this is the design pattern we came up with - trying to mimic a graph representation of a neural network.
