[]- The Alden- Crustacean Arthropods with a centaur-like body layout. They are incredibly resilient to thermal energy due to a weak stratosphere. Bleeding off excess heat by "opening" their shell and loosening their plates to rapidly let out waste heat. They have numerous eyes that are ideal for ranges under slightly under a half mile. They use manipulator tendrils that can leave the interior of the claws.

[]- Velim Empath- Cephalopod's who have grown to a larger stature, with a more potent brain. They are imbued with a natural ability to on skin to skin contact, induce powerful empathy with one another. This has allowed them to communicate with other organisms, something they excel at. They have already managed to annex several aquatic or amphibious races. And have only spread to a handful of systems after repelling an Orkoid Invasion.

[]- Fleshripper Mimics- Amphibious Carnivorous Starfish that are able to quickly swim through water, or rapidly scuttle on land in bursts of absurd speed. They are dependent on water, and are incredibly vicious swarm hunters. Once latched on barbed tendrils pierce the flesh of the assaulted creature. Paralyzing and overwhelming the bodies impulses. In this way they can cover and control a host body while they feed. They additionally can pile together and temporarily meld for lack of a better term. Suggesting that they harvest dna samples from prey to correctly reshape their exterior.
