Yes! You're correct. They're not finished and are more of a prototype to help me develop the game with two races in play so the systems are properly rounded out.
That being said, there are three new summons planned. They should be added relatively soon. Plus, Ancients, as well as Humans, will constantly get more and more things to build, including void-based objects. I try to add more blueprints each update. The update I'm currently working on has a ton. The next update will also let Humans use the void via the new tech tree.
One thing--which you may or may not care about--is the addition of more story elements for each race as development progresses. That's an area I've left completely untouched as I work on the core game. But I do want to have more scenarios, artifacts, and historical figures appear which are based on the race you select. These would give lots of backstory to them and the world and make them feel even more unique.
