Fern was an bioengineered concavenator so he was a bluevein. A bluevein is a concavenator with extra lizard genome but there mane genome influence was from blue tongued skinks and birds of paradise. The near extinction of these genome influencers now makes it illegal to make one but having one isn't. Now they are being bred by multiple governments so they don't die out.
