The cosmic laws and entities of the ST’RCK-5 multi-macroverse are both similar and alien to our own. There are planets and suns, with various types of life on some of them, but the ways these bodies work is not always exactly the same as ours.
I never got around to digitally creating Katu originally (or creating Katu in any visually sense), but there was a concept of it on paper (as described in this post); so, to me, the 1st version of Katu was the concept version just discussed about, while the 2nd version is this one (which was my second attempt, ever, to make a planet in Photoshop – back in 2015). I made various changes to the specific names of the landmarks of this planet and the details of its history – and even up to the point of this post, I still am not 100% sure on what will be called what, or what will happen exactly when (which is all in the works) – but a lot of what is in this image is still relevant to the 3rd version that has been created recently (which can be seen here, among other posts). A big difference between this version and the 3rd one is the number of giant rivers cross the entire face of the world; whereas, there is now only two rivers, compared to the four (which the idea could always make a comeback, if proven advantageous). Either way, no matter which version I go with in the end, Katu will be a primal place full of cat-like creatures who are obsessed with their two greatest assets: their children and their traditions.
