After noticing the lack of sci twi centered groups ( that I know of ) I begun my own, I hope you enjoy.
The banner image was created by obluse from devianart, its not the full image, so if you wanna see it then I recommend clicking the link to their account (assuming the account is still there by the time you've read this): https://0bluse.deviantart.com/art/MLP-Tracking-520781631
Edit: so apparently there was another sci twi centered group, oops?
