Demon Ref
 
This week we have concept art for a species simply called "demons," a race of brutal and primitive reptilian creatures that are very gladiatorial in nature.  Their society is built upon dominance and brute strength, with many deaths occurring over minor disagreements.  As you can see they employ a number of different weapons, including their shield and even specially built tail weapons.  They are also very agile when on all fours.

These guys have a steed that goes along with them that you can see here: https://www.patreon.com/posts/2758063
